About

To evaluate a star-shaped incision technique to thick-gingiva and thingingiva patients treated with implant-supported fixed prosthesis. The star-shaped incision would be an effective and simple method to reconstruct gingival papillae and avoid the gingival recession in thick-gingiva patients treated with implant-supported fixed prosthesis, and it is worthy of clinical extend.

Full description

Objective: To evaluate a star-shaped incision technique to thick-gingiva and thin-gingiva patients treated with implant-supported fixed prosthesis. Methods and Materials: 24 patients received cross-shaped incision were assigned into thick-gingiva group (16 cases) and thin-gingiva group (8 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: 24 patients

Sex: All

Ages: 22 to 58 years old

Volunteers: Accepts Healthy Volunteers

Inclusion and exclusion criteria

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 this study had been treated with one bone-level implant insertion in the premolar or molar region. The patients had insufficient gingival papilla height (referred to contralateral natural tooth which also had insufficient gingival papilla height) and at least 2 mm of keratinized tissue width around the implant.

Exclusion criteria

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

Trial design

24 participants in 2 patient groups

thick-gingiva group

Description:

After the insertion of the probe into the facial aspect of the sulcus through the gingival margin, the simple visual method is based on the transparency of the periodontal probe through the gingival margin while probing the buccal sulcus at the midfacial aspect of the tooth. When the outline of the underlying periodontal probe can't be seen through the gingival, the gingival phenotype is considered thick.

thin-gingiva group

Description:

After the insertion of the probe into the facial aspect of the sulcus through the gingival margin, the simple visual method is based on the transparency of the periodontal probe through the gingival margin while probing the buccal sulcus at the midfacial aspect of the tooth. When the outline of the underlying periodontal probe can be seen through the gingival, the gingival phenotype is considered thin.
