Inclusion Criteria

This prospective case series study considered all consecutive patients were eligible to participate, if they had at least three adjacent missing teeth in the posterior region of the mandible or maxilla and were treated with a 3-unit FDP on 2 implants. All patients were screened using clinical and radiographic examinations to determine if they met all of the following inclusion criteria:
-over 18 years of age and capable of understanding and giving informed consent;
-sufficient horizontal and vertical space to place a three-unit FDP;
-sufficient bone levels at the proposed implant sites to place implants with a length of at least 8.5mm and a width of 4mm;
-the presence of natural antagonistic teeth or a prosthetic construction.

Exclusion Criteria

Any of the following was regarded as a criterion for exclusion from the study:
-uncontrolled pathological processes in the oral cavity;
-known or suspected current malignancy;
-history of radiation therapy in the head and neck region;
-history of chemotherapy within 5 years prior to surgery;
-systemic or local disease, condition or medication that could compromise postoperative healing and/or osseointegration;
-is a smoker (and intends to continue);
-regular alcohol and/or drug use.
