Different Intraorbital Implant Situations and Ocular Prosthetic Rehabilitation

Aggarwal H, Kumar P, Eachempati P, Alvi HA

PMID: 26447725 DOI: 10.1111/jopr.12369

Enucleation is the removal of the entire globe of the eye and a portion of the optic nerve, while evisceration involves the removal of the contents of the globe leaving the sclera, extraocular muscles, and optic nerve. Following enucleation or evisceration, intraorbital implants are routinely placed to enhance the prosthetic outcome in addition to restoring the lost orbital volume. Current practice employs intraorbital implants made of nonporous silicone, hydroxyapatite, or porous polyethylene. Intraorbital implant selection and placement, being a highly demanding procedure in terms of knowledge, skill, and expertise, may be associated with a multiplicity of technical and surgical errors. Complications are usually minimal with these implants, but they do occur. The literature reveals many articles related to intraorbital implants, their benefits, and complications; however, the literature regarding the effect of various intraorbital implant situations on the subsequent prosthetic rehabilitation is markedly scarce. Moreover, the need for interdisciplinary surgical and prosthetic interventions required for successful rehabilitation in cases of compromised implant situations has been underemphasized. Hence, this review aimed to evaluate the effect of different intraorbital implant situations on ocular rehabilitation and the required interdisciplinary surgical and prosthetic treatment approach for rehabilitation of enucleated/eviscerated sockets with compromised implant situations, to provide a critical appraisal, and to present a simplified management strategy.

Transfemoral prosthesis suspension systems: a systematic review of the literature

Gholizadeh H, Abu Osman NA, Eshraghi A, Ali S

Am J Phys Med Rehabil, 2014 Sep;93(9):809-23.

PMID: 24743451 DOI: 10.1097/PHM.0000000000000094

The purpose of this study was to find the scientific evidence pertaining to various transfemoral suspension systems to provide selection criteria for clinicians. To this end, databases of PubMed, Web of Science, and ScienceDirect were explored. The following key words, as well as their combinations and synonyms, were used for the search: transfemoral prosthesis, prosthetic suspension, lower limb prosthesis, above-knee prosthesis, prosthetic liner, transfemoral, and prosthetic socket. The study design, research instrument, sampling method, outcome measures, and protocols of articles were reviewed. On the basis of the selection criteria, 16 articles (11 prospective studies and 5 surveys) were reviewed. The main causes of reluctance to prosthesis, aside from energy expenditure, were socket-related problems such as discomfort, perspiration, and skin problems. Osseointegration was a suspension option, yet it is rarely applied because of several drawbacks, such as extended rehabilitation process, risk for fracture, and infection along with excessive cost. In conclusion, no clinical evidence was found as a "standard" system of suspension and socket design for all transfemoral amputees. However, among various suspension systems for transfemoral amputees, the soft insert or double socket was favored by most users in terms of function and comfort.

Conventional open repair for Thoracoabdominal aortic aneurysm (TAA) is associated with high morbidity and mortality. Spinal cord ischemia (SCI), renal failure, bowel ischemia and mortality are established complications following this procedure. With the advent of endovascular stent technology, various novel approaches have been described to reduce these complications, namely fenestrated stent graft and hybrid procedure. We present a case of hybrid procedure in a pseudoaneurysm of descending thoracic aorta done in Kuala Lumpur Hospital.

PMID: 22582560 MyJurnal

A 68 year old man with significant cardiorespiratory risks factors presented with a ruptured thoracic aortic aneurysm (TAA). This was treated by emergency thoracic endovascular aneurysm repair (TEVAR) under general anaesthesia (GA). An incidental abdominal aortic aneurysm (AAA) was not treated. Eight months later, he presented with ruptured AAA. Due to the patient's compromised respiratory system, he underwent endovascular aneurysm repair (EVAR) under local anaesthesia (LA). He had a smoother post-operation recovery compared to the first repair under GA.

PMID: 19379469 DOI: 10.1111/j.1540-8183.2009.00443.x

Percutaneous bifurcation intervention is usually sufficient with a single-stent strategy. When the double-stent strategy is employed, higher restenosis and target lesion revascularization (TLR) rates are observed, especially at the side-branch ostium. The results may be improved, however, with refinement in techniques, for example, final kissing balloon inflation and double kissing balloon inflation.

Fulltext Modular endoprosthetic replacement after total femur resection for malignant bone tumor

Faisham WI, Zulmi W, Halim AS

Med J Malaysia, 2005 Jul;60 Suppl C:45-8.

PMID: 16381283

Total femur endoprothesis is an alternative replacement for massive malignant bone tumor with intramedullary extension or skip lesion. Four patients underwent total femoral resection and replacement with megaprosthesis: three had primary malignant bone tumor and one had salvage procedure for aseptic loosening of the distal femoral replacement. Tumor-free margins were achieved in all patients with two patients required vascularized latissimus dorsi free flap cover for reconstruction of soft tissue defects. The average follow-up was 24 months (range 16 - 60 months). All four patients were still alive with three of them being disease-free and one survived even with the presence of lung metastasis. The functional results obtained were either excellent or good in all patients in accordance to the Musculoskeletal Tumors Society grading system.

Fulltext Imaging of Osteo-odontokeratoprosthesis(OOKP) Using Multidetector Computed Tomography: A UKMMC Experience

Abu Bakar N, Lee CL

Med J Malaysia, 2013;68(1):73-5.

PMID: 23466774

Osteo-odontokeratoprosthesis (OOKP) surgery is a technique used to replace damaged cornea in blind patients for whom cadaveric transplantation is not feasible. OOKP surgery is a complex procedure requiring lifetime follow-up. The preservation of the osteo-odontolamina is the vital feature in maintaining the stability of the OOKP. Early detection of lamina resorption enables early prophylactic measures to be taken and prevent resorption-related complications. This case illustrates the radiological findings of the first OOKP surgery in Malaysia and the role of multidetector computed tomography (MDCT) in postoperative management of OOKP surgery.

Missing teeth can be due to hypodontia, trauma or extraction. In general, the options for treatment depend on the severity of the hypodontia and the severity of the malocclusion. Occasionally, the space from missing teeth has to be maintained for prosthetic replacement and require an orthodontic/restorative approach. It is very important to ensure the space maintained is adequate for aesthetic reason so that it can be replaced with a prosthesis after the orthodontic treatment is completed. This article discusses a new innovation and clinical technique for maintaining this space during orthodontic treatment by using an acrylic tooth with several modifications. This innovation will be illustrated using two cases.

This clinical case report details the clinical sequence of a 78-year-old male receiving prosthetic rehabilitation using an implant-supported screwretained fixed partial denture. Despite the limitations imposed, the aesthetic and functional demands of the patient were fulfilled by this prosthetic rehabilitation. The importance of detailed prosthetic planning and evaluation prior to implant surgery is essential, therefore ideally, it should be done by the same operator or a team of operators working together. Problems can arise when the construction of the prosthesis is performed by other people who are not involved in the planning stage.

MyJurnal

Tumour surgery for locally extensive malignant neoplasms of the extremity will sometimes result in extensive composite soft tissue defect. Local flaps are usually inadequate to cover these large defects. More than one tissue flap might be required to cover any exposed neurovascular structures, bone or prosthesis. We present two cases where two composite flaps were simultaneously used to cover extensive surgical defects after ablative tumour resections in the extremity. These resulted in uncomplicated wound healing and limb salvage.

Clinical outcomes of implant-supported and tooth-supported fixed prostheses fabricated from digital versus analogue impression: a systematic review and meta-analysis

Mahat NS, Shetty NY, Kohli S, Jamayet NB, Patil P

Evid Based Dent, 2023 Sep;24(3):142.

PMID: 37369705 DOI: 10.1038/s41432-023-00904-5

OBJECTIVE: To analyze the clinical outcomes of implant-supported prostheses and tooth-supported fixed prostheses, fabricated from digital and conventional impression.

MATERIALS AND METHODS: The literature search was carried out on two electronic databases (PubMed and Cochrane Library). Randomized controlled trials (RCT) published from January 2011 to September 2022 were included. The bias risk was evaluated using Cochrane Risk of Bias Tool 2.0. Further screening was done for meta-analysis according to modified Newcastle-Ottawa scoring criteria. Forest plot was generated using a statistical method of inverse variance of random effect with 95% confidence interval.

RESULTS: A total of 8 randomized controlled trials were included for systematic review out of which four studies were based on tooth-supported fixed prosthesis and remaining four were based on implant-supported prosthesis. Further screening was conducted and three studies were eligible for meta-analysis. Tooth-supported fixed prosthesis fabricated from digital impression showed no significant difference in the marginal fit in any region measured, except for occlusal region where conventional impression showed more favorable marginal fit. Implant-supported prosthesis fabricated from digital impression showed survival rates ranging from 97.3 to 100% and there was no statistically significant difference in marginal bone loss (p = 0.14).

CONCLUSION: Implant-supported prostheses fabricated from digital and conventional impressions show no significant differences in their clinical outcomes. Tooth-supported fixed prostheses fabricated from digital impression have shown favorable findings in terms of marginal fit. Despite that, there is still lack of clinical trials with larger sample size and longer follow-up periods. Future studies that fulfill these two criteria are deemed necessary.

Fulltext Passive Fit in Screw Retained Multi-unit Implant Prosthesis Understanding and Achieving: A Review of the Literature

Buzayan MM, Yunus NB

J Indian Prosthodont Soc, 2014 Mar;14(1):16-23.

PMID: 24604993 DOI: 10.1007/s13191-013-0343-x

One of the considerable challenges for screw-retained multi-unit implant prosthesis is achieving a passive fit of the prosthesis' superstructure to the implants. This passive fit is supposed to be one of the most vital requirements for the maintenance of the osseointegration. On the other hand, the misfit of the implant supported superstructure may lead to unfavourable complications, which can be mechanical or biological in nature. The manifestations of these complications may range from fracture of various components in the implant system, pain, marginal bone loss, and even loss of osseointegration. Thus, minimizing the misfit and optimizing the passive fit should be a prerequisite for implant survival and success. The purpose of this article is to present and summarize some aspects of the passive fit achieving and improving methods. The literature review was performed through Science Direct, Pubmed, and Google database. They were searched in English using the following combinations of keywords: passive fit, implant misfit and framework misfit. Articles were selected on the basis of whether they had sufficient information related to framework misfit's related factors, passive fit and its achievement techniques, marginal bone changes relation with the misfit, implant impression techniques and splinting concept. The related references were selected in order to emphasize the importance of the passive fit achievement and the misfit minimizing. Despite the fact that the literature presents considerable information regarding the framework's misfit, there was not consistency in literature on a specified number or even a range to be the acceptable level of misfit. On the other hand, a review of the literature revealed that the complete passive fit still remains a tricky goal to be achieved by the prosthodontist.

Fulltext Lost wax-bolus technique to process closed hollow obturator with uniform wall thickness using single flasking procedure

Patil PG, Nimbalkar-Patil S

J Indian Prosthodont Soc, 2017 2 22;17(1):84-88.

PMID: 28216851 DOI: 10.4103/0972-4052.176538

INTRODUCTION: Maxillary obturator prosthesis is more frequent treatment modality than surgical reconstruction for maxillectomy in patients suffering from oral cancer. The obturators often become heavy and hence are hollowed out in the defect portion to reduce its weight as a standard practice.

MATERIALS AND METHODS: The processing technique described the incorporation of the preshaped "wax-bolus" during packing procedure of the Obturtor prosthesis and eliminated later by melting it once the curing procedure is completed.

RESULTS: This article is a single step procedure resulting into the closed-hollow obturator as single unit with uniform wall thickness around the hollow space ensuring the least possible weight of the hollow obturator.

CONCLUSION: This processing technique achieves predictable internal dimension of the hollow space providing uniform wall thickness of the obturator.

Fulltext Investigation on three-dimensional printed prosthetics leg sockets coated with different reinforcement materials: analysis on mechanical strength and microstructural

Ramlee MH, Ammarullah MI, Mohd Sukri NS, Faidzul Hassan NS, Baharuddin MH, Abdul Kadir MR

Sci Rep, 2024 Mar 21;14(1):6842.

PMID: 38514731 DOI: 10.1038/s41598-024-57454-8

Previous research has primarily focused on pre-processing parameters such as design, material selection, and printing techniques to improve the strength of 3D-printed prosthetic leg sockets. However, these methods fail to address the major challenges that arise post-printing, namely failures at the distal end of the socket and susceptibility to shear failure. Addressing this gap, the study aims to enhance the mechanical properties of 3D-printed prosthetic leg sockets through post-processing techniques. Fifteen PLA + prosthetic leg sockets are fabricated and reinforced with four materials: carbon fiber, carbon-Kevlar fiber, fiberglass, and cement. Mechanical and microstructural properties of the sockets are evaluated through axial compression testing and scanning electron microscopy (SEM). Results highlight superior attributes of cement-reinforced sockets, exhibiting significantly higher yield strength (up to 89.57% more than counterparts) and higher Young's modulus (up to 76.15% greater). SEM reveals correlations between microstructural properties and socket strength. These findings deepen the comprehension of 3D-printed prosthetic leg socket post-processing, presenting optimization prospects. Future research can focus on refining fabrication techniques, exploring alternative reinforcement materials, and investigating the long-term durability and functionality of post-processed 3D-printed prosthetic leg sockets.
