About

To evaluate a cross-shaped incision technique to thick-gingiva and thin-gingiva patients treated with implant-supported fixed prosthesis.

Full description

Objective: To evaluate a cross-shaped incision technique to thick-gingiva and thin-gingiva patients treated with implant-supported fixed prosthesis. Methods and Materials: 55 patients received cross-shaped incision were assigned into thick-gingiva group (29 cases) and thin-gingiva group (26 cases). Follow-up examination was carried out 3 and 12 months after final restoration. Clinical and radiographic evaluation including gingival papilla height, modified plaque index, modified sulcus bleeding index, periodontal depth, and crestal marginal bone level were utilized.

Enrollment: 55 patients

Sex: All

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

1. Good general health, no chronic systemic diseases.
2. All subjects included in this study needed to have one missing premolar or molar teeth with adjacent natural teeth.
3. All subjects included in the study had been treated with one bone-level implant insertion in the premolar or molar region.

Exclusion criteria

1. Active periodontal infections.
2. Heavy smoking habit (>10 cigarettes per day).

Trial design

55 participants in 2 patient groups

thick-gingiva group

Description:

After insertion of the probe into the facial aspect of the sulcus, the peri-implant biotype can be categorized as thick-gingiva (outline if the probe cannot be seen through the gingival)

thin-gingiva group

Description:

After insertion of the probe into the facial aspect of the sulcus, the peri-implant biotype can be categorized as thin-gingiva (outline of the probe can be seen through the gingival)

Treatment:

Diagnostic Test: The biotype of gingival
