简要总结
This study will compare two incision designs to allow for coronal gingival/mucosal flap advancement and tissue augmentation with acellular dermal matrix (ADM) graft around teeth with gingival recession and a lack of adequate keratinized gingiva.
To the investigators knowledge, these two techniques have not been compared for differences in clinical (amount of root coverage, tissue thickness, and esthetics) and patient-centered outcomes (pain, swelling, change in daily activities) in a controlled study.
详细描述
Research data and daily clinical observations reveal that teeth with gingival recession and a lack of adequate keratinized tissue (KT) are more prone to persistent gingival inflammation, dentinal sensitivity, radicular (root) caries (tooth decay), faster periodontal attachment loss, and compromised plaque control. Soft tissue grating (by various techniques) aims at changing the quality, quantity and placement of the soft tissue around teeth by covering exposed root surfaces and creating or increasing the zone of keratinized mucosa (KM) surrounding the affected teeth. Both techniques tested have shown good clinical outcomes with regard to root coverage, but clinical reports of the VISTA technique and other similar techniques suggest that patients experience a decrease in site morbidity and discomfort post-operatively. This study will compare two surgical incision designs used in conjunction with coronally advanced flap (CAF) and acellular dermal matrix (ADM)
Specific aims for this project include the evaluation of:
- Percentage of root coverage at 6 and 12 months following grafting with VISTA and sulcular tunnel access with ADM
- KT width at 6 and 12 month following grafting with VISTA and sulcular tunnel access with ADM
- Change in tissue thickness of the grafted sites at 6 and 12 months
- Practitioner-assessed esthetic outcomes using a standardized pink esthetic scale (PES) at 6 and 12 months postoperatively
- Patient-assessed esthetic outcomes at 6 and 12 months post-operatively
- Patient centered outcomes including pain, bleeding, swelling, change in daily activities at 1 week and 1 month postoperatively

- •English speaking
- •At least 18 years old
- •Must be a patient of the UAB Dental School
- •Able to read and understand informed consent document
- •One or more adjacent teeth (up to four) with Miller class I or II gingival recession defects and less than or equal to 2mm of KT at each site to be treated.
- •Presence of periodontally healthy, non-carious neighboring teeth, healthy implants or edentulous ridges on either side of the involved site(s)

排除标准
- •Non-English speaking
- •Less than 18 years old
- •Smokers/tobacco users (>10 cigarettes/day)
- •Patients with systemic pathologies or conditions contraindicating oral surgical procedures or adversely affecting wound healing
- •Presence of active periodontal disease or radiographic interproximal bone loss or tooth malposition, which would yield a Miller class III or IV categorization for the recession defect.
