Oral Rehabilitation With Orthognathic Surgery After Dental Implant Placement for Class III Malocclusion With Skeletal Asymmetry and Posterior Bite Collapse

Abstract

Increasing numbers of older patients are seeking orthognathic surgery to treat jaw deformity. However, orthodontic and orthognathic surgical treatment is difficult in cases without occlusal vertical stop.A 55-year-old male presented with class III malocclusion and mandibular protrusion including esthetic problems and posterior bite collapse. He underwent dental implant treatment to reconstruct an occlusal vertical stop prior to orthognathic surgery. His occlusal function and esthetic problems improved after surgery, and his skeletal and occlusal stability has been maintained for 6 years.Dental implant placement at appropriate positions could help to determine the position of the proximal segment at orthognathic surgery, and could shorten the time required to restore esthetic and occlusal function. This case demonstrates how skeletal and dental stability can be maintained long after surgery in a patient with jaw deformity and posterior bite collapse.

Multiprofessional approach for class III malocclusion rehabilitation with autogenous calvarial bone graft followed by Le Fort 1 osteotomy and implant-supported prostheses – case report

“…Then, proceeding final step, to the orthognathic surgery was performed with grafts and implants stable and osseointegrated, all of which increases the success rate of implant osseointegration as already demonstrated in other studies (Branemark et al, 1977;Chiapasco et al, 2007;de Avila et al, 2014;De Santis et al, 2012;Ferri et al, 2008;Gil et al, 2008;Jacobson & Starr, 2008;Keller et al, 1999;Ohba et al, 2015;Soehardi et al, 2015). It was also decided to reduce the chin, improving the patient's facial proportion and, consequently, facial aesthetics.…”

Strategy for oral rehabilitation concomitant to orthognathic surgery: implantoprosthetic treatment

“…Cases of single or multiple edentulous spaces With the ageing of populations worldwide, prioritization will be given to those patients who already have implants that could complicate planned treatments. The poor positioning of implants could compromise the orthodontic process, orthognathic surgery, and consequently the prosthetic treatment 24 .…”
