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.

Arm Intervention/treatment
Experimental: PASI
PASI dental prosthesis delivery
Procedure: PASI

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.

Active Comparator: PAC
PAC dental prosthesis delivery
Procedure: PAC
Metalic standard removable partial denture, the standard treatment, will be delivered in 4 steps at Day 7, D14, D21, D28 after inclusion, as classically.

Primary Outcome Measures :
  1. prosthetic success rate [ Time Frame: 5 years after prosthesis delivery ]

Secondary Outcome Measures :
  1. prosthetic success rate [ Time Frame: 6 months, 1 year, 2 years, 3 years and 4 years after prosthesis delivery ]
