Detailed Description
Primary objective: to evaluate the efficacy of the specific implant management currently offered to XLH patients according to the recommendations, in terms of implant survival.
Secondary objectives: 1. to study the evolution of the peri-implant bone level within 2 years after implant placement ; 2. to study the evolution of the stability of the peri-implant tissues in the 2 years following the installation of the implant ; 3. to describe the osseointegration of the implant 6 months after insertion ; 4. to evaluate the effectiveness of the specific implant management in terms of the delay in occurrence of the first implant loss of patients ; 5. to describe the reasons for removal of the implants ; 6. to evaluate the satisfaction of the implant treated patient ; 7. to describe the occurrence of dental plaque, suppuration or bleeding around implants.
Experimental plan: this is an observational prospective study with historical control group (retrospective compendium) comparing XLH-specific implant management (prior phosphorus / vitamin D supplementation and prolonged implant healing) to non-specific management. For prospective inclusion (patients with specific implant management) patients will be recruited from adults with XLH as part of an oral assessment. After inclusion each patient will be followed 24 months. The surgical treatment and the clinical and radiographic follow-up correspond to the specific management proposed in our service to the patients presenting an XLH. Prior to implant placement, a cone-beam computed tomography scan will confirm adequate bone volume for implant placement. Implant surgery will be performed under local anesthesia following the protocols recommended by the manufacturer. The follow-up is done during the healing period and the realization of the implant prosthesis (6 months after surgery) then 12, 18 and 24 months after the surgery. It will include a clinical and radiographic examination, and will verify the presence of the implant in the mouth (survival of the implant), and the stability of the peri-implant tissues (level of attachment and bone level)
