About

The present study is a human, prospective, parallel, randomised controlled clinical trial conducted to check the interproximal bone loss of Z shaped incision over conventional sulcular H shaped incision.The trial is in accordance with the Consolidated Standards of Reporting Trials (CONSORT) criteria, 2010.

Full description

Twenty healthy individuals satisfying the inclusion and exclusion criteria were recruited for the study. A detailed, thorough medical and dental history was obtained and each patient was subjected to comprehensive clinical and radiological examination. All patients were informed about the nature of the study, the surgical procedure involved, potential benefits and risks associated with the surgical procedure and written informed consent were obtained from all patients. In the test group patients Z shaped incision was done to place implants and H shaped sulcular incision was placed in control group.

The clinical and radiographic parameters were recorded at baseline,24 hours,7days, three months and six months postoperatively.

Enrollment: 20 patients

---

20 participants in 2 patient groups

Test group

Experimental group

Description:

Two horizontal incisions placed 1-2 mm away from the papilla of the teeth adjacent to the edentulous space following the mesial and distal contour of the teeth. These two horizontal incisions are then connected by an oblique incision from the disto-buccal to mesio lingual point angles.

Treatment:

Procedure: Z shaped incision

Control group

Experimental group

Description:

Sulcular incisions placed in the proximal sides of the adjacent tooth facing the edentulous space in a bucco lingual direction extending between the proximal line angles Mid crestal incision performed in the attached mucosa of the edentulous area connecting the sulcular incisions of the adjacent teeth from the distal to mesial tooth

Treatment:

Procedure: H shaped incision
