Primary outcome parameter
The primary outcome variable is the mean marginal bone loss, for which the Marginal Bone Levels (MBL) between placement of the restoration (T0) and after 3 years (T3) are determined from standardized, long cone intraoral radiographs, by measuring from the edge of the implant to the bone-to-implant contact, both mesially and distally.
Achtergrond van het onderzoek
The aim of this prospective case-series study is to evaluate and document the clinical performance, complications and patient-reported outcomes of single implant-supported two-unit cantilever restorations in the posterior region. A total of 20 consecutive patients will be treated with a single implant in the (pre-) molar region. After an osseointegration period of 3 months a single crown with a mesial cantilever is provided. All data will be collected beforehand, after providing the restoration and yearly during a follow-up period of 3 years.

mplant placement
Implant treatment consists of the placement of a single implant (Conelog Progressive-Line, Promote Plus 4.3mm with a minimal length of 11mm, Camlog Biotechnologies GmbH, Basel, Switzerland) under local anesthesia. Implant placement will be conducted in accordance with the manufacturers' recommendations and is based on a digital planning and drill guide. It is performed by two experienced implant specialists. A protocol for antibiotic prophylaxis consisting of amoxicillin (2 grams, intraorally, 1 hour prior to surgery) and a mouth rinse (for two weeks, 0.2% Chlorhexidine, 2 times a day, starting 1 day prior to surgery) will be followed. A cover screw will be placed and de wound will be closed primarily for an uncompromised healing.
Restorative procedure
After a minimum of 3 month the implant is uncovered and a healing abutment is placed. Restorative treatment commences a week after uncovering the implant. A digital impression is made. A screw retained crown luted to an individual titanium abutment and with a cantilever is provided according to standard restorative procedures. Occlusion is checked meticulously and oral hygiene instruction is provided. Recall visits are scheduled.
