Brief Summary

Evaluation of Soft and Hard Tissue Changes After Immediate Implant Placement With Sticky Tooth Versus Autogenous Tooth Graft for management of Cases With Labial Plate Dehiscence

Conditions

Immediate Implant

Outcome Measures

Primary Outcomes (1)

• Radiographic width of bone labial to the implant

  Amount of bone labial to the implant will be measured perpendicular to the vertical line of the implant surface at the implant neck level or the top of the buccal bone (which is regarded as 0 mm), 3 mm and 6 mm apical to the implant neck Each measurement will be recorded at different times

  1 year

Secondary Outcomes (10)

• Radiographic horizontal bucco-palatal bone changes

  1 year

• Radiographic vertical bone changes

  1 year

• Esthetic evaluation (The pink esthetic score)

  1 year

• Implant stability

  6 months

• Gingival Thickness

  1 year

Intervention group

EXPERIMENTAL

sticky tooth preparation: * patient's venous blood will be collected using a 21 g needle with a butterfly handle. * The blood in the test tubes will be centrifuged at 700 rpm for 3 min for women and 4 min for men because of a different hematocrit. * The liquid PRF fraction will be collected using a sterile syringe. It gently will be mixed with the demineralized dentin granules and allowed for five-ten minutes for polymerization in order to produce a sticky tooth.

Procedure: immediate implant augmented with sticky tooth

Control group

ACTIVE COMPARATOR

Autogenous demineralized dentin graft preparation * Extracted teeth will be cleaned from periodontal ligaments, cementum, soft tissue attachment, caries, or restorations (if present), using a high-speed fine finishing stone and saline irrigation. * The pulp will be removed, using a root canal instrument. Subsequently, the remaining dentin will be cut into pieces. These pieces of dentin will be ground using a bone mill to produce dentin particles. * The sorted particles will be immersed in 70% ethanol and 4% H2O2 in a sterile container to remove any soft tissue remnants, bacteria, and smear layer. * Tooth particles will be demineralized using 0.6N HCl for 30 minutes to expose the dentine organic matrix. * After demineralization, the materials will be washed with phosphate-buffered saline (PBS) and dried with sterile gauze.

Procedure: immediate implant augmented with autogenous tooth graft

Interventions

immediate implant augmented with sticky tooth PROCEDURE

* Topical anesthesia will be administered using an infiltration technique. * Atraumatic extraction will be done with the aid of periotome and Luxators. * The extraction socket will be debrided to remove any residual debris or granulation tissue. * Full-thickness midcrestal incision and vertical releasing incision on the distal side will be made, and a vertical releasing incision on the mesial side will be made if necessary. The extraction socket and the labial bone defect will be exposed by buccal and palatal flap reflection. * Implant insertion will be performed according to the manufacturer's instruction, and then the implant will be inserted 2mm apical to the alveolar bone crest with adequate primary stability. * The gap between the implant and the defect of the facial bone will be filled with the sticky tooth to reach enough buccal bone supported and then will be covered with absorbable barrier collagen membranes. * Finally, the flap will be repositioned and sutured.
