Clinical case: Efficacy of Geistlich Mucograft® for lack of keratinized tissue and peri-implantitis
BioBrief - Soft-Tissue Regeneration
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 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 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.
Keys to Success
- Flap design
- Implant surface modification and polishing
- Adaptation of soft-tissue substitute
- Apical positioning of the partial thickness flap
- Peri-implant supportive therapy
