Jaw, Edentulous, Partially
Conditions
Brief summary
The trial is designed as a consecutive enrollment prospective one-center study. A minimum of 30 patients will be included in the study. At implant installation, the patient will be randomized to receive one of the two types of implants (Control: internal hexagon connection implants (CON.INT); Test: Morse taper connection implants (MT-12)). Samples of peri-implant crevicular fluid (PICF) and intrasulcular plaque will be collected at -21 (second-stage surgery), -14 (impressions), 0 (Baseline: prosthesis delivery), 7 days and 1, 3, 6, 12 months. Prosthesis will be fabricated and delivered as usual, i.e., approximately two weeks after the impressions are taken.
Interventions
Placement of the MT-12 dental implant with Morse taper implant-abutment connection
Placement of the CON.INT dental implant with internal hexagon implant-abutment connection
