Summary

Black triangles, also known as open gingival embrasures, are usually the result of the lack of papilla fill interdentally. With the improvement of dental procedures and materials, more attention has been directed to improving this unesthetic occurrence. Improvement of papilla loss (black triangle) can be mainly categorized into non-surgical and surgical techniques with most surgical modalities focused on a minimally invasive approach due to the restricted working area and blood supply to the papilla. Collagen matrix offers strong mechanical properties while promoting tissue healing and hence is used in many periodontal plastic surgeries (gum surgeries). However, the outcome of collagen matrix in treating papilla loss has not been studied yet. This study aimed to see at the clinical effects of collagen matrix in papilla augmentation using a minimally invasive surgical approach.

Patients with papillae loss were selected and Collagen matrix (Geistlich Fibro-Gide) used to stabilize the affected area with a minimally invasive surgical procedure. Papilla height gain, texture and color will be assessed pre-operatively, three and six months postoperatively. in addition, probing depth, clinical attachment level and keratinized tissue width will also be assessed.

Conditions

  • Dental Papilla Loss, Black Triangles
  • Black Traingles
  • Interdental Papillae Reconstruction
  • Interdental Papilla Augmentation
  • Interdental Papilla Loss

Interventions

PROCEDURE

papillary unit advancement

collagen matrix augmentation in papilla area using tunneling technique, up to my knowledge, it's the first time to use collagen matrix in treating papilla, in less invasive approach, only though tunneling with no primary and secondary incisions. so, the technique is designed to be less invasive, maximizing papillary blood supply. and to use xeno collagen matrix instead of connective tissue graft used in previous study. so \~ less morbidity, less postoperative pain with no Donar graft site .
