Effectiveness of Xenogenic Collagen Matrix in Modification of Mucosal Phenotype Around Dental Implants

Effectiveness of Xenogenic Collagen Matrix in Modification of Mucosal Phenotype Around Dental Implants

Aim of the study The rationale for conducting the present study is to evaluate the efficacy of porcine collagen matrix in the management of defective width of keratinized mucosa around dental implant.

Therefore, the primary objective is to evaluate the integration of porcine collagen matrix with the recipient site and measuring the amount gained of keratinized mucosa. The secondary objective is to assess the pink esthetic score around dental implant following porcine collagen matrix compared to the free gingiva graft.

3. Inadequate keratinized soft tissue <2 mm (13).
4. Favorable pattern of occlusion.
5. Good oral hygiene.
6. Patient ability to comply with the required recall visits.

Exclusion Criteria:

1. Insufficient bone width (less than 6 mm) mesiodistal or buccolingually.
2. Patients having any uncontrolled systemic disease which could affect bone healing.
3. Patients treated with radiotherapy to the head and neck area within the past 12 months.
4. Heavy Smokers (more than 20 cigarette per day) according to WHO.
5. Inability or unwillingness to return for follow-up visits.
