Detailed Description
PICO P: single pontic site with deficient ridge. I: Soft tissue augmentation with partially de-epithelized connective tissue graft.
C: Soft tissue augmentation with Mucograft. O: Soft tissue biotype, Soft tissue volume, pain score and patient satisfaction.
Preoperative measures:
- All subjects will pass through phase I therapy (Supragingival scalling, subgingival debridement and oral hygiene instructions) before any surgical procedures.
- After 4 weeks, all subjects will be examined to determine patient compliance with oral hygiene procedures (tooth brushing twice daily and chlorhexidine HCL 1.25% mouthwash twice daily).
- Eligible patients will be randomized before being enrolled in the study. (T-1 +4 weeks)
- Study casts for case study will be fabricated and clinical photographs will be taken.
- Assessment of edentulous defect site and neighboring teeth will be performed by scanning the study casts.
Surgical phase (T0):
The same operator (N M) will perform all procedures under local anesthesia (4% articaine with 1/200 000 adrenaline Solution), using a local infiltration technique.
The recipient site will be prepared using 15c-blad creating a full-thickness coronal dissection and a partial thickness apical dissection creating a vestibular pouch.
The grafting procedure then performed and graft will be fixed by suturing at the periphery of the flap using 5/0 suture material and the rest will be inserted in the vestibular pouch.
The patient will have printed post-surgical instruction and precautions.
Intervention for control group :
- The recipient site will be prepared with a full-thickness coronal dissection and a partial thickness apical dissection to creat a vestibular pouch.
- The acellular matrix (Mucograft®) will be sutured using 5/0 suture material around the defect margin and secured in the vestibular pouch.
Intervention for test group :
- The recipient site will be prepared with a full-thickness coronal dissection and a partial thickness apical dissection vestibular pouch.
The graft which is composed of two parts:The coronal part, which is epithelialized
- The apical part, which is formed of connective tissue only.
- On the defect area, the crestal surface is de-epithelialized with a beveled incision and the apical surface is prepared with a partial-thickness dissection with two vertical- releasing incisions extended apically, without involving the adjacent papillae, in order to create a pouch area.
- The onlay section (epithelialized area) of the graft will be sutured on the crestal surface of the defect, while the inlay section (connective tissue) will be inserted and secured in the vestibular pouch area.
- Post-operative care:
As with any regenerative site, caution must be exercised in post-operative care and during oral hygiene practices at or near the surgical site. After 12 hours 875 mg of Amoxicillin and 125 mg of Clavulanic acid tablet (1 g Amoxicillin Clavulanate) twice daily for 7 days, anti-inflammatory tablet (Amphiltirne ) if the patient need ,maximum three times/day and chlorhexidine HCL 1.25% mouth wash mouthwash twice daily are prescribed. Sutures will be removed after 14 days. (12)
* Follow-up (T1, T2,T3):
(T1):2 weeks post-operatively sutures removal . (T2) 3 months post-operatively appointments will be assigned for the prosthetic preparation and temporization for 2 weeks (T3): 6 months post-operatively appointments will be assigned for the prosthetic delivery and fill in the Questionnaire.
Criteria for discontinuing intervention:
- Infection and sloughing of the graft.
- if the patient wouldn't commit to the follow-ups.
- Strategies to improve adherence to intervention protocol:
Patient preparation in terms of improving oral hygiene and first phase therapy procedures will be performed for patient to doctor trust. Complete information concerning the protocol will be provided and simplified to the patient with reasoning of all the steps included as the importance of the follow up visits and home medication.
Relevant concomitant care and interventions that are permitted or prohibited during the trial:
Postoperatively the patients will be using analgesics, oral antibiotic therapy, and chlorhexidine HCL 1.25% mouthwash mouthwash for at two week.

Intervention / Treatment |

Active Comparator: Mucograft
Soft tissue augmentation of the defective alveolar ridge using Mucograft inside the prepared vestibular pouch leaving part of the mucograft exposed at the crestal area and will be sutured using 5/0 suture material around the defect margin and secured in the vestibular pouch.
|
For preprosthetic defects, a standard mucosal augmentation procedure, which is well reported in the literature, was performed. The surgical site produced by the surgery leaves a "denuded area" supraperiosteally that is addressed by "grafting" with a xenogeneic collagen membrane (Mucograft). purpose of the surgery is to improve the quantity of attached mucosa to facilitate the final dental reconstruction

Experimental: Partially de-epithelialized connective tissue graft
Soft tissue augmentation of the defective alveolar ridge using Partially de-epithelialized connective tissue graft by preparing vestibular pouch at the defect site and place the de-epithelialized part inside the pouch leaving the epithelialized part sutured and exposed at the crestal area
|
graft procedures to obtain simultaneous tissue augmentation in the horizontal and vertical dimensions.
The donor site was prepared with a full-thickness coronal dissection and a partial-thickness apical dissection.The objectives were to use a single procedure to achieve simultaneously apico-coronal and buccolingual augmentation,to have a smaller open wound in the donor site and less patient discomfort, and to guarantee better revascularization of the onlay section aided by the submerged connective tissue section of the graft.
