Patient‐specific titanium onlay eminoplasty: A novel protocol for treatment of recurrent temporomandibular joint dislocation

Abstract

PurposeThe present study aimed to introduce an accurate, less morbid and less time‐consuming approach that secures the stability of the condylar movement's range for treating recurrent TMJ dislocations.MethodsFive patients were treated by surgical implantation of bilateral patient‐specific titanium onlay eminoplasties; each implant was virtually designed using specific software and milled from grade V titanium blocks. Intraoperatively, each implant was fixed with three mini‐screws along the lateral aspect of the zygomatic arch.ResultsThe follow‐up period ranged from 6 months to 1 year, which targeted the assessment of the maximal incisal mouth opening (MIO). The mean preoperative maximal incisal mouth opening figured (47.8 mm) vs (33.2 mm) for that recorded postoperatively. One patient reported postoperative slight unilateral pain that was gradually diminished through the first postoperative month.ConclusionThe innovated patient‐specific titanium eminoplasty represents an accurate alternative for treatment of chronic recurrent TMJ dislocation.

The ESTMJS (European Society of Temporomandibular Joint Surgeons) Consensus and Evidence-Based Recommendations on Management of Condylar Dislocation

“…Surgical techniques should be considered where non-surgical and minimally invasive techniques are not successful in avoiding recurrent dislocation [14]. Surgical methods for treatment of recurrent dislocations include eminectomy to facilitate spontaneous reduction [48][49][50][51][52][53], restrictive techniques for prevention of recurrence of dislocation (blocking or redressment procedures) [54][55][56][57], and surgical correction of capsular ligament complex [58][59][60][61]. After any surgical treatment, patients should, for a few days, eat soft foods only and refrain from opening the mouth widely [17,24,41,50,57,60].…”

Efeito Da Terapia Periodontal Sobre Níveis De Glicemia E Perfil Lipídico Em Pacientes Com Periodontite

“…Entretanto, em caso de insucesso, a cirurgia aberta da articulação deve ser considerada, justificando a realização da eminectomia para o caso apresentado. Existem diversas abordagens cirúrgicas para a luxação recidivante da ATM e a escolha da técnica ideal ainda é uma questão discutível, tendo em vista que a maioria dos protocolos cirúrgicos demanda morbidade da região, tempo intraoperatório longo e risco de resultados imprevisíveis (IHAB et al, 2020).…”

10 year experience with patient-specific midfacial reconstruction - A single-center study

“…Moreover, titanium alloys have shown biocompatibility and promising results in several craniofacial applications [24][25][26][27] . Recently patient-specific implants were widely applied in craniofacial regions including eminence prosthesis [24] and mandibular reconstruction devices [22,28] .…”

“…Moreover, titanium alloys have shown biocompatibility and promising results in several craniofacial applications [24][25][26][27] . Recently patient-specific implants were widely applied in craniofacial regions including eminence prosthesis [24] and mandibular reconstruction devices [22,28] . The use of patient specific implants for midfacial defects was reported in combination with a vascularized flap [29] , other than that it has not been largely found in literature.…”
