Details and patient eligibility

About

Patients were randomly distributed into two groups (G1 and G2), all patients were treated by a submerged dental implant protocol and free gingival graft (FGG) harvested from the palate as follows:

• Group 1 (G1), received the FGG two months before implant placement.
• Group 2 (G2), received the FGG at the time of second-stage surgery (i.e. at the time of healing abutment placement).

All periodontal and radiographic assessments were done by the same operator who was neither involved in the evaluation nor the distribution process. The operator did all the evaluation steps and was completely blinded to the treatment protocol.

Full description

In this investigation, a randomized clinical trial was employed. The patient's randomization was completed by one of the department's senior residents, who was not involved in the trial and was unaware of any relevant treatment plan. A computer-generated randomization list used a randomization table to perform the randomization (SPSS v23.0). Patients were randomly distributed into two groups (G1 and G2), all patients were treated by a submerged dental implant protocol and FGG harvested from the palate. All patients received a thorough description of all procedures involved in the study. Signing a written consent was mandatory for being enrolled in the study. Complete medical and dental histories were recorded for all patients and complete clinical intraoral and extraoral examinations were done for all patients.

Selected patients were questioned about the cause and time of extractions, whether extractions were because of periodontal disease, dental decay or other causes. Previous experiences with dental procedures were also discussed. Intraoral photographs were taken to record the existing condition of teeth and mucosa before implant placement.

Trial design

20 participants in 2 patient groups

Group 1

Description:

Group 1 participants underwent free gingival graft placement two months before implant placement.
