“…They concluded that a patient-fitted implant required less adaptation, which decreases surgery time and the risk of injury to the skull base and alveolar nerve. 37 Similarly, Abramowicz et al 38 set out to evaluate the necessity for the use of a patient-fitted implant in 22 cases by evaluating whether a stock Biomet implant could be fitted to the stereolithographic models of patients who were treated with a TMJ Concepts device. They found that in 23% of all sites, no fit could be achieved by means of a stock implant.…”

“…39 Screw position and length can be determined using a patient-fitted approach to prevent damage to the inferior alveolar nerve. 5,38 For simple TJR, the patient-fitted mandibular component can be inserted via a miniretromandibular incision, diminishing the risk of lesioning the mandibular branch of the facial nerve, in a similar fashion as described by Biglioli and Colletti 41 for condylar fractures.…”

Purpose: This article aims to compare the difference in postoperative results in patients treated with either a patient-specific (PSI) or a stock temporomandibular total joint replacement system. Materials and Methods: The investigators performed a systematic review concerning postoperative results after placement of either a stock total joint replacement system or a PSI. PubMed Central, Web of Science, Cochrane Library Plus, Wiley Online Library, and EMBASE were used to conduct this search. All articles up to August 15, 2018, were scrutinized. All included articles were nonrandomized cohort studies. Maximal mouth opening (MMO) and Visual Analog Scale (VAS) scores for pain and diet before and after surgery were evaluated. The Methodological Index for NonRandomized Studies scale was used for quality assessment. Weighted mean difference was calculated and pooled by meta-analysis using random-effect models. Results: The search identified 1581 articles, of which 15 were included. The average risk of bias was low. Both systems achieved significant increases in MMO and decreased VAS pain scores at 1, 2, and 3 years after surgery. No significant difference was found between the system types. Both achieved significant improvements in dietary VAS scores, with a more significant improvement for stock implants. Conclusions: Due to the lack of detailed diagnostic evaluation tools allowing proper start-point categorization, there is a significant risk for selection bias in the pooled data. The PSI is more frequently chosen for cases with more significant joint degeneration, skewing postoperative results. A patient-fitted implant can provide significant operative and patient-centered advantages over a stock implant, which will likely be confirmed when observational cohort studies have included indications like the ones for stock prostheses. Furthermore, while current US Food and Drug Administration-approved stock implants contain cobalt -chromium -molybdenum, the newly manufactured PSI are made of titanium alloy, diminishing the risks of morbidity and implant failure.

“…In studies by Briceño et al (2013) [26] with customized aloplastic unilateral replacements (48.1%) or bilateral replacements (52.19%) the most frequent etiologies were mutilation of TMJ by gunshot wounds or previous surgery (22%) followed by ankylosis (18.5). Another study [1] highlights that the main causes were osteoarthritis, failures in previous operations, ankylosis and arthritis.…”

The aim of this study was to investigate the clinical efficacy of temporomandibular alloplastic prosthesis for full reconstruction of the temporomandibular joint. The total sample was 44 patients, including 17 men and 27 women. Clinical parameters such as deviation and limitation of mouth opening and facial asymmetry, and subjective criteria such as headache, difficulty chewing, local pain and the degree of patient satisfaction postoperatively were used. The mean of the follow up was approximately 5 years. It was observed that the mouth opening postoperatively was higher than that of preoperative showing an average increase of 14.6 ± 8.04 mm. Similarly, the measure of laterality and protrusion also increased significantly postoperatively. Reports of snap, crackle, headache, facial asymmetry and mainly local pain significantly decreased (Fisher exact test, p <0.05) after surgery. It was observed that 33 (75%) subjects had improvement in both chewing and socializing, and 37 (84.1%) showed improvement in chewing and 40 (90.9%) showed improvement in social life. The results of this research showed that studied the prosthesis is an effective and predictable option for full reconstruction of the TMJ.

“…Two categories of total TMJ TJR prosthesis have been studied: standard prostheses, where the surgeon needs to adapt the patient's anatomical features; and custom-made prostheses for each clinical situation (Figure 1) [9,[21][22][23]. On the manufacturing of prostheses, titanium alloys are used to promote osseointegration in the mandible ramus and articular fossa.…”

In the last years, several materials and design have been assessed in an attempt to improve the mechanical performance of temporomandibular joint total joint replacement (TMJ TJR) prostheses. However, the wear of the TMJ TJR condyle to the polymer-based fossa component during loading and sliding movements. That promotes the release of debris and risks of toxicity to the surrounding tissues. The purpose of this study was to perform a narrative literature review on the wear of TMJ TJR sliding contacts and potential toxicity of metallic debris to the patients. Previous studies reported a significant deterioration of the sliding contact surfaces of TMJ TJR prostheses. Material loss as a result of wear can cause a TMJ TJR condyle/fossa mismatch and the modification of the contact pressure and chewing loading. As a further consequence of wear, metal particles are released to the surrounding tissues with a high risk of local tissue and systemic toxicity through the bloodstream. The presence of particles induces the stimulation of inflammatory reactions depending on the concentration and size of debris. Thus, CoCr-based condyle release metallic ions and sub-micron particles that can be engulfed by macrophages or internalized by other tissue cells. The wear and material loss of TMJ TJR could be decreased by design optimization and novel materials with low friction and contact pressure. That consequently decrease the amount of metallic ions and particles to the surrounding tissues, preventing peri-prosthetic inflammatory reactions.
