BIOBRIEF
The Buccal Pedicle Flap for Peri-Implant Soft Tissue Volume
THE SITUATION
Patient presented with a fistula buccal on tooth #9 associated with a chronic peri-apical lesion and external root resorption. Also tooth #8 showed a chronic peri-apical lesion. Her chief complaint was the misalignment of her teeth. The clinical situation revealed the presence of bleeding upon probing and generalized moderate periodontal disease (Stage II, Grade I) as well as multiple endodontic failures.
THE RISK PROFILE
| Low Risk | Medium Risk | High Risk | |
|---|---|---|---|
| Patient’s health | Intact immune system | Light smoker | Impaired immune system |
| Patient’s esthetic requirements | Low | Medium | High |
| Height of smile line | Low | Medium | High |
| Gingival biotype | Thick – “low scalloped” | Medium – “medium scalloped” | Thin – “high scalloped” |
| Shape of dental crowns | Rectangular | Triangular | |
| Infection at implant sight | None | Chronic | Acute |
| Bone height at adjacent tooth site | ≤ 5 mm from contact point | 5.5 – 6.5 mm from contact point | ≥ 7 mm from contact point |
| Restorative status of adjacent tooth | Intact | Restored | |
| Width of tooth gap | 1 tooth (≥ 7 mm) | 1 tooth (≤ 7 mm) | 2 teeth or more |
| Soft-tissue anatomy | Intact | Compromised | |
| Bone anatomy of the alveolar ridge | No defect | Horizontal defect | Vertical defect |

The aim of the treatment is to eradicate periodontal disease and restore esthetics and function. Treatment planning: non-surgical and surgical periodontal treatment, orthodontic alignment, extraction of both central incisors, immediate implant placement and Guided Bone Regeneration with Geistlich Bio-Oss®, peri-implant soft tissue boosting with a buccal pedicle flap and full ceramic CAD-CAM restorations.
“Orthodontic treatment must be postponed because of the presence of periodontal disease. A thin biotype and a high smile line needs to be taken into consideration.”
THE OUTCOME
The final outcome at 8 weeks is showing pink esthetics as well as biomimetics and function. The use of the buccal pedicle flap allowed the increased volume of the peri-implant mucosa with a minimally invasive approach. The combination of Geistlich Fibro-Gide® and a buccal pedicle flap had the main advantage of reducing the morbidity generally associated with CT harvesting.
