Horizontal Ridge Augmentation in Maxillary Esthetic Zone Using Bovine Bone Graft Versus Extended Sticky Bone With Simultaneous Implant Placement

9. maj 2026 opdateret af: Mansoura University
This research is designed to evaluate and compare the clinical and radiographic outcomes of bovine bone graft (Medpark) versus extended sticky bone used for horizontal augmentation of atrophied esthetic area of maxillary ridge associated with simultaneous implant placement.

Studieoversigt

Detaljeret beskrivelse

Patient selection This study will involve sixteen implants inserted in patients with missing upper tooth / teeth in the esthetic zone accompanied by horizontal alveolar ridge resorption, seeking future tooth replacement. The patients will be selected from the Outpatient Clinic of Oral and Maxillofacial Surgery Department, Faculty of Dentistry, Mansoura University

Inclusion Criteria:

  1. Patient aged 18-45 years.
  2. Cooperative patient with high motivation and acceptable oral hygiene.
  3. Maxillary narrow ridge in the esthetic zone that needed horizontal bone augmentation. (Class I Siebert classification). (22)
  4. No deep undercut at the ridge in the buccal aspect.
  5. The presence of enough keratinized gingiva(≥3mm).(23)
  6. Sufficient inter-arch space to accommodate the future prosthesis. (24)
  7. Patients able to comply with the required recall visits.

Exclusion criteria:

  1. Local and / or systemic conditions that contraindicate the placement of dental implant or surgery
  2. Smokers
  3. Pregnancy.
  4. Parafunctional habits, including bruxism and clenching.

Intervention / Behandling
Eksperimentel: Eight dental implants were inserted simultaneously with horizontal ridge augmentation using Medpark
For group I, Medpark bone graft was prepared by hydration with sterile saline, gentle mixing, and allowed to partially set before application to the defect site. For group II, extended sticky bone (ESB) was prepared by centrifugation of autologous blood followed by preparation of ALB-PRF and mixing with bone particulates (50:50 allograft: xenograft) to obtain the final graft materia

The oral cavity was prepared using 0.12% chlorhexidine mouth rinse for one minute. Local anesthesia was administered using articaine 4% with 1:100,000 epinephrine. A full-thickness mucoperiosteal flap was reflected using a crestal horizontal incision with vertical releasing incisions to expose the surgical site.

Osteotomy preparation was performed using a pilot drill to the planned depth at 800-850 rpm under copious sterile saline irrigation, followed by sequential drilling according to the manufacturer's protocol until the final implant size was achieved. The sterile implant was then inserted using a ratchet wrench. Implant stability was immediately assessed using resonance frequency analysis (Osstell device), and cover screws were subsequently placed.

Tidsramme
Implant Stability Quotient (ISQ) Values Assessed by Resonance Frequency Analysis
Tidsramme: Baseline and 6 months after implant placement

Implant stability was assessed using resonance frequency analysis (RFA) with the Osstell device and expressed as Implant Stability Quotient (ISQ) values. ISQ scores range from 1 to 100, with higher scores indicating greater implant stability and osseointegration.

High stability: ISQ > 70 Medium stability: ISQ 60-69 Low stability: ISQ < 60

Measurements were recorded immediately after implant placement and at the 6-month follow-up.
