Comparison of customized and standard healing abutments in patients receiving dental implants for missing back teeth to assess gum tissue and bone levels

INTERVENTION: Intervention1: Customized healing abutment: A prefabricated titanium healing abutment will be selected according to implant platform diameter and customized chairside using light‐cured composite resin to reproduce the desired cervical contour and emergence profile. The customized healing abutment will be placed immediately after implant placement and torqued according to the manufacturers recommended torque. Control Intervention1: Prefabricated titanium healing abutment: A standardized prefabricated titanium healing abutment will be selected according to implant platform diameter and placed without modification immediately after implant placement. The abutment will be torqued according to the manufacturers instructions. Control Intervention2: Prefabricated healing abutment: A standardized prefabricated titanium healing abutment will be selected according to implant platform diameter and placed without modification immediately after implant placement. The abutment will be torqued according to the manufacturers instructions. CONDITION: Health Condition 1: K084‐ Partial loss of teeth PRIMARY OUTCOME: Change in transgingival mucosal thickness in mm around implants restored with customized and prefabricated healing abutments in posterior single tooth implant restorations.Timepoint: Baseline, 1 month, 3 months and 6 months after implant placement. SECONDARY OUTCOME: Buccolingual emergence profile width in mm around implants restored with customized and prefabricated healing abutments in posterior single tooth implant restorations.Timepoint: Baseline, 1 month, 3 months and 6 months after implant placement. Marginal bone level changes in mm around implants restored with customized and prefabricated healing abutments in posterior single tooth implant restorations.Timepoint: Baseline, 1 month, 3 months and 6 months after implant placement. Peri‐implant probing depth in mm around implants restored with customized and prefabricated healing abutments in posterior single tooth implant restorations.Timepoint: Baseline, 1 month, 3 months and 6 months after implant placement. INCLUSION CRITERIA: 1. Patients medically fit for minor oral surgery. 2. Patients aged 18 to 45 years. 3. Patients of either gender. 4. Patients with good oral hygiene who are willing to undergo dental implant placement and follow up. 5. Patients with a partially edentulous single unit space in the molar region of the mandibular arch. 6. Periodontally healthy patients without any pathology involving the implant site. 7. Patients with adequate bone volume at the implant site without the need for bone grafting. 8. Non smoking, non alcoholic and systemically healthy patients. 9. Patients willing to participate voluntarily and provide written informed consent. 10. Implants placed with primary stability greater than or equal to 35 Ncm and measurable baseline ISQ values.
