“…However, for patients without previous interventions and normal anatomy, "stock" prosthesis is a good alternative, eliminating costs and elaboration time 22 , according to our study in which most of the patients (25 to 56.8%) had not undergone previous surgery and obtained excellent results with the Biomet stock prosthesis [1, 8,15,17,[23][24][25] .…”

“…It is noted that for laterality and protrusion, a bigger number of patients with a reduction of these movements was obtained, which is a common fact in postoperative condylar prosthesis installation, and that is related to the detachment of the lateral pterygoid muscles responsible for this function [2,24]. Despite involvement of pterygoid and masseter (which are disinserted) during the placement of the prosthesis, this does not interfere with its functionality, clinical and functional improvement after installing the prosthesis are obtained as well as result predictability [29].…”

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.

“…Also the Stock prostheses is not appropriate for some patients with extensive tumors or severe deformities, intraoperative time consume to prepare the mandibular the fossa and mandibular ramus fit with the prosthesis. In contrast, the custom-made prosthesis is more expensive, but it is highly accurate, and it is also considered the prosthesis of choice in patients with major TMJ and mandibular defects [23,24].…”

“…The eminence area irregularities and the fossa bottom with complex depressions result in the instability of the prostheses. Surgeons must take care when removing irregularities by a bone bur and then place the fossa component directly because they got to preserve enough bone to retain the screws on zygomatic arch [24].…”

Temporomandibular joint (TMJ) and the associated muscles turn possible mandibular movements as a complex engineering appliance that may be affected by signs and symptoms such as pain, including in head and neck areas, abnormal jaw movement and clicking or crepitus sounds, classified as temporomandibular disorders (TMD). Some procedures such as discopexy, eminectomy, or arthroplasties, which we consider conservative, can result in ankylosis, even resorption and joint degeneration, limiting surgical options to treat TMJ. The alloplastic prosthesis becomes an option. Total joint reconstruction using prosthesis becomes the treatment choice during the following conditions: previous surgeries including autogenous grafts fail; presence of arthritic diseases; fibrous or bony ankylosis; tumors involving the TMJ; loss of vertical posterior mandible dimension by other TMJ pathologies; and previous prosthetic joint fail. The use of TMJ prosthesis, when compared to other reconstructive procedures, provides immediate function, reducing the duration of surgery and hospitalization time. Disadvantages of the TMJ prosthesis include high cost, prosthesis failure, functional mandibular movements loss, such as protrusion and laterality, and limited fit of stock prosthesis.

“…Although there are some reports on the application of ankylosis6789, most of them are custom ones which are much easier to implant intraoperatively than standard ones. In order to make the bone fit the prostheses accurately, we used computer-assisted technique to guide bone trimming and implantation of the Biomet standard prostheses10111213.…”

Temporomandibular joint (TMJ) ankylosis is a refractory disease that is difficult to predictably treat. This study evaluated the prognosis of using standard alloplastic TMJ prostheses for the treatment of TMJ ankylosis in Chinese patients with severe mandibular deficiency. Patients treated from 2013 to 2015 were reviewed. The computer-aided design and manufacture (CAD/CAM) technique was used to guide bony mass removal and locate the TMJ prosthesis (Biomet, USA). Eleven patients were included in this study. All prostheses were successfully installed and stabilized intraoperatively. In 4 patients with severe mandibular deficiency, their mandibular ramus was elongated by the TMJ prosthesis and 2 patients were combined with Le Fort I osteotomy guided by digital templates. Their mean chin advancement was 10.19 mm. Their SNB and ramus heights were also significantly improved after operation (P < 0.05). There was no prosthesis loosening, breakage, or infection leading to removal after a mean follow-up period of 22 months (range, 12-31mos.). Mouth opening was significantly improved from 5.5 mm preoperatively to 31.5 mm postoperatively. TMJ reconstruction with standard alloplastic prosthesis is a reliable treatment for ankylosis, especially in recurrent cases. By CAD/CAM technique, it can correct jaw deformities simultaneously and produce stable results.
