Recently, a reduced width of keratinized tissue around dental implants has been considered a risk indicator for the severity of peri-implant mucositis (Grischke and coworkers 2019) even in highly compliant, periodontally healthy patients. Based on this observation, in cases of peri-implant mucositis associated with insufficient keratinized tissue, a soft-tissue graft may be indicated to reduce the risk of recurrence. Figures 13a-yillustrate a case where the treatment of severe peri-implant mucositis was accompanied by the application of an FGG graft to improve the quality of the peri-implant soft tissue and to improve the chances of successful long-term maintenance.

Fig 13b The crown and abutment were removed to provide access to the inflamed area.
Fig 13c The treatment consisted of careful debridement and gentle cleaning of the area with titanium curettes and an ultrasonic device with a PTFE-coated tip.

Dentists should focus on more than just the implants and prosthetic restorations to achieve long-term clinical success.
Patients must be strongly motivated to adhere strictly to SPT and should be made to understand that supportive care is a key factor in enhancing the long-term outcome by controlling reinfection. Although the topic remains controversial due to a lack of proper scientific evidence, there is still enough clinical evidence that adequate keratinized tissue and vestibular depth may positively impact the health of the peri-implant mucosa. Furthermore, soft-tissue augmentation around implants in specific clinical situations may be of major help in ensuring long-term stability. Only if both the clinician and the patient understand the importance of a custom-planned SPT program—which may also include mucogingival surgery—can the risk of biological complications be reduced to a minimum.
