Immediate Implants Connective Tissue Graft
Conditions
Brief summary
Evaluation of soft and hard tissue changes after immediate implant placement with connective tissue graft and bone as a control group and connective tissue graft only as a test group.
Detailed description
This randomized clinical trial will evaluate the effect of using connective tissue graft and bone graft versus connective tissue graft, with customized healing abutments during immediate implant placement on volumetric mid facial recession .In patients with type I socket who need extraction in the anterior maxilla.
Interventions
PROCEDUREImmediate implant and connective tissue graft
Tooth extraction and immediate implant placement as mentioned. Connective tissue grafts will be harvested from the hard palate and placed at the implant sites in a supra-periosteal partial dissection pouch prepared at the buccal aspect without using vertical incisions and without flap elevation. Sutures will be used to stabilize the graft in its desired place. Followed by customized healing abutment.
PROCEDUREImmediate implant with connective tissue graft and bone graft
Tooth extraction and immediate implant placement as mentioned. Connective tissue grafts will be harvested from the hard palate and placed at the implant sites in a supra-periosteal partial dissection pouch prepared at the buccal aspect without using vertical incisions and without flap elevation. Xenograft will placed to fill the jumping gap.Sutures will be used to stabilize the graft in its desired place. Followed by customized healing abutment.

Inclusion criteria
* Patient-related criteria: * Adults at or above the age of 18. * Non-restorable maxillary anterior or premolar tooth requiring extraction and needed an implant placing therapy. * The failing tooth will have adjacent and opposing natural teeth. * Sufficient mesial-distal and interocclusal space for placement of the implant and definitive restoration. * Able to tolerate surgical periodontal procedures. * Full mouth plaque and bleeding scores less than 20%. * Compliance with the maintenance program. * Provide informed consent. * Accepts the one-year follow-up period. Teeth related criteria: * Intact thick biotype gingival tissue with at least 2mm band of keratinized tissue. * Intact socket wall before the extraction, buccal bone thickness ≤1mm assessed by CBCT. * Sufficient apical bone to place an immediate implant with minimum primary stability of 30Ncm
Exclusion criteria
* Patients diagnosed with periodontal diseases. * Current or previous smokers. * Pregnant and lactating females. * Patients with medical conditions that would compromise the surgical procedures; uncontrolled diabetes mellitus, taking IV Bis-phosphonates for treatment of osteoporosis. * Patients with active infection related at the site of implant/bone graft placement. * Patients with parafunctional habits
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Volumetric Analysis of Mid-facial recession | Preoperative,3months,6months and 12 months | 3d viewer will be used to the the midfacial recession . |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Bone formed labial to the implant | Preoperative and 1 year | — |
| Horizontal labio-palatal bone collapse | Preoperative and 1 year | — |
| Vertical crestal bone level changes | Preoperative and 1 year | — |
| Gingival biotype | Preoperative, 6 months and 12 months | — |
| Volumetric analysis of Interdental papillae height | Preoperative , 3 months, 6 months and 12 months | — |
| Full mouth bleeding score (FMBS) | Preoperative, 6months and 12 months | (0,1,2,3) 0:normal gingiva, 1: No bleeding , 2:bleeding on probing, 3:tendency to spontaneous bleeding. |
| Pain and discomfort | At 1,3 and 7 days after the surgery | will be assessed using the visual analog scale VAS as recorded by the patient 1, 3 and 7 days after the surgery. The patients will mark the pain perception in a non-numerical 100 mm line ranging from no pain=0 (left) to very painful=100 (right). It will be given a numerical value by measuring in millimeters the distance from the left end of the line . |
| Full mouth plaque score (FMPS) | Preoperative, 6 months and 12 months | 0 : no plaque scored at gingival margin 1: Plaque scored at gingival margin FMPS: Number of sites scored with plaque/Number of sites evaluated x 100 |
| Pink Esthetic Score | at 12 months | PES is based on seven parameters; mesial papilla, distal papilla, soft-tissue level, soft tissue contour, alveolar process deficiency, soft-tissue color, and texture. The peri-implant mucosa will be evaluated by the seven index points.The contralateral tooth and the adjacent soft tissue served as reference using a 0-1-2 scoring system, with 0 being the lowest and 2 being the highest value. |
| Volumetric analysis of buccal contour | Preoperative,3months,6months and 12 months | — |
