Tooth Loss
Conditions
Brief summary
This study aims to compare the therapeutic efficiency of implant-secured removable partial denture (PASI) with the therapeutic efficiency of the metalic standard removable partial denture (PAC) in the treatment of intermediate extended-gap (4 adjacent teeth). The therapeutic efficiency will be assessed by the 5 years-prosthetic success rate.
Interventions
PROCEDUREPASI
Implant-secured removable partial denture will be delivered in 2 large steps: implant delivery followed by denture delivery. * Implant delivery will take 4 dental consultations : a pre-implant study at Day14 after inclusion, the surgical implant insertion at D28 after inclusion, stitches removal at D35 after inclusion, and finally functional implant delivery between 3 or 6 month after surgery (to allow implant osteointegration). * Denture delivery will take 6 weekly dental consultations between Week 3 and Week 8 after the functional implant delivery.
PROCEDUREPAC
Metalic standard removable partial denture, the standard treatment, will be delivered in 4 steps at Day 7, D14, D21, D28 after inclusion, as classically.

Inclusion criteria
* Patients with at least a 4 to 6 adjacent teeth intermediate extended-gap (excluding wisdom teeth) in the upper or lower jaw. * Patients with at least 4 conservable teeth by dental arch, without major occlusal trouble. * Patients with healthy periodontium, allowing metalic standard removable partial denture delivery : bleeding on periodontal probing for a duration less than 30 seconds, Osteolysis of the alveolar ridge less or equal to 50%, attachment loss less or equal to 5mm * Patients with a sufficient bone volume for implant placement, without prior bone supply.
Exclusion criteria
