Keratinized Tissue Augmentation Using Porcine Collagen Matrix (Mucoderm®) Around Dental Implant

Keratinized Tissue Augmentation Using Porcine Collagen Matrix (Mucoderm®) Around Dental Implant: A Randomized Clinical Study

Aim of the Study To evaluate the using of porcine collagen matrix for keratinized tissue augmentation around delayed dental implant.

Primary Outcome:

Peri-implant keratinized mucosal width and thickness following the use of porcine collagen matrix using (Mucoderm®-Botiss gmbh) compared to the gold standard FGG augmentation.

Secondary Outcome:

1. Crestal bone change (CBC)
2. Pocket depth (PD)
3. Bleeding on probing (BOP)
4. Plaque index (PI) PICOT

P: Population:

Patient with suitable ridge dimension for delayed implant placement.

I: Intervention:

Implant insertion followed by porcine collagen matrix soft tissue augmentation

C: Control:

Autogenous FGG

O: Outcomes

• Enhancing keratinized mucosal width and thickness

• Evaluating :

  1. Crestal bone change (CBC)
  2. perimplant Pocket depth (PD)
  3. Bleeding on probing (BOP)
  4. Plaque index (PI)
  5. Modified PES. T: Time A 6 months follow up .

this study aiming to augment KMW with FGG and MUCODERM following apically positioned flap the primary outcomes to measure is KMW and MT
