Clinical and Radiographic Evaluation of a Cross-shaped Incision Technique

Clinical and Radiographic Evaluation of a Cross-shaped Incision Technique to Thick-gingiva and Thin-gingiva Patients Treated With Implant-supported Fixed Prosthesis

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

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.

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).
