Detailed Description
The aim of the study is to evaluate ridge width gain in patients with narrow alveolar ridges followingc osseodensification as compared to ridge splitting with simultaneous implant placement using CBCT.
Interventions: I. Pre-operative phase: Clinical Examination: 1. Visual examination, palpation and inspection of the entire oral and Para-oral tissues. 2. Preoperative alginate impressions for both the maxillary and the mandibular Ridges. 3. Full mouth scaling and root planing, followed by oral hygiene instructions. 4. The Bucco-Lingual/Palatal alveolar ridge width measurement at site of interest using a bone caliper. 5. Study casts will be made in order to properly evaluate the inter-arch space, occlusion type and direction of forces in regard to the site of the future implant. Radiographic Examination: 1. A panoramic radiograph for screening purposes: - estimating the residual bone height. - Verify the absence of any pathology in the bone. 2. Cone beam computed Tomography (CBCT) for Diagnostic purposes: - Detect the Bucco-lingual/palatal alveolar ridge width and height at the site of interest. - Detect approximation to any anatomical boundaries (e.g.mental foramen, maxillary sinus floor.) -Detect bone type. II. Surgical phase: All procedures will be done under strictly aseptic conditions 1. Patients will be anesthetized at the surgical site by the appropriate method using Articaine Hydrochloride 4%. 2. At the site a horizontal incision will be created, extending the entire length of the edentulous area, extending one tooth mesial and distal. Anterior and/or posterior vertical releasing incision will be made as needed. 3. Full thickness mucoperiosteal ~ap will be raised with complete exposure of the alveolar bone. 4. Bone width will be recon}rmed intrasurgically using a bone caliper. Measurements will be taken at around 1 mm below the crestal margin, to the nearest 0.5mm. Alveolar ridge width measurements will be repeated at second stage surgery. 5. A.For the intervention: 1. Drilling f bone will commence using the Pilot Drill to the desired depth (Drill speed 800-1500 rpm with copious irrigation). 2. Osseodensification drilling will begin with the narrowest Densah Bur. (Counterclockwise drill speed 800-1500 rpm with copious irrigation). If when running the bur into the osteotomy a feeling of haptic feedback of pushing up and out of the osteotomy, repetitively lifting off and reapplying pressure with a pumping motion will be applied until the desired depth is reached. 3. Densah Burs will be used sequentially in small increments. As the bur diameter increases, the bone will slowly expand to the final diameter. 4. The osteotomy final preparation diameter would be an average diameter that measures 0.5-0.8 mm smaller than the implant average diameter in soft bone, and In hard bone, diameter that measures 0.2-0.5 mm smaller than the implant average diameter. 5. Implant placement using the drill motor initially, then Finishing placement of the implant to depth with a torque-indicating wrench. 6. If < 1mm of buccal bone thickness has resulted after osseodensification, bone grafting post implant placement and complete implant coverage will be considered 5.B.For the control: 1. A bone crestal incision will be created, using the piezo-electric surgical tips. The cut will be done through the cortical bone to reach the trabecular bone. 2. One/two vertical cuts will be created by piezo-drill as needed connecting, to the crestal cut. 3. Conventional Drills will be used for osteotomy preparation by wedging it between the two plates of bone. 4. The implant with the proper length and diameter will be gradually engaged to separate the buccal and Lingual/palatal bone until full seating is achieved. 6. Cover screws will be placed on the implants. 7.Closure of the ~ap will be done by interrupted sutures using 4-0 resorbable suture materials. III. Post-operative phase: Post-operative instructions and medication: Patient is recommended to: 1. Maintain a soft diet to avoid trauma to the surgical site. 2. Place a cold compress super}cially on the skin overlying the surgical site immediately. Apply for 30 minutes, then off for 20-30 minutes. This should be done on a near continuous basis (or as much as possible) for the }first 48 hours. 3. Maintain Oral hygiene but avoid surgical site for the }rst 4 days after surgery. 4. Medications (Ferrigno et al. 2005)( Garcez-Filho et al.2015) • Augmentin* (1g tablets) will be prescribed twice daily for 5 days to avoid possibility of infection. • Ibuprofen** 600mg four times daily for one week. • Voltarene*** (75 mg injection I.M.) will be used in case of severe pain, as a rescue. • Hexitol**** 0.12% chlorhexidine mouth rinse for 2 weeks. 5. Sutures will be removed after 2 weeks 6. Final restoration will be completed after 6 months - Augmentin 1g. Medical union pharmaceuticals co.
