Therapeutic Area: Peri-Implantitis
BIOBRIEF
Clinical Efficacy of Geistlich Mucograft® in Regeneration of Oral Mucosa Combined with the Surgical Treatment of Peri-implantitis in Implants with Lack of Keratinized Tissue
THE SITUATION
Adult patient, non-smoker and without relevant systemic history, attends to clinic referring peri-implant tissue inflammation, bleeding and brushing discomfort around her implant in the upper jaw. Clinically peri-implant pocket depth > 5 mm, bleeding and suppuration on probing were observed. Furthermore, the implant presented < 2 mm of keratinized mucosa and radiographic horizontal bone loss.
THE RISK PROFILE
Low Risk | Medium Risk | High Risk | |
---|---|---|---|
Patient’s health | Intact immune system Non-smoker | Light smoker | Impaired immune system Heavy smoker |
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 APPROACH
Intrasulcular incision was made and a mucosal partial thickness flap was raised. The recipient site was prepared by sharp disection in order to create a periosteal bed free of any muscle attachment. Peri-implant granulation tissue was removed and implantoplasty was performed. Finally, Geistlich Mucograft® was used to support the gain of keratinized tissue. Thus, the collagen matrix was sutured with the resulting flap apically at the base of the newly created vestibulum.
THE OUTCOME
After two years follow-up, the successful outcome can be observed in terms of clinical peri-implant parameters, gain of keratinized mucosa without significant graft shrinkage and stability of vertical position of the mucosal margin.
