Horizontal ridge expansion and implant placement using screws: a report of two cases.

Kim YK, Kim SG - J Korean Assoc Oral Maxillofac Surg (2014)

Bottom Line: We placed 11 implants in 6 patients, and one implant failed during osseointegration but it was replaced immediately after removal and successful prosthetic treatments were completed.During these surgeries, buccal cortical plate complete fractures do not occur.Inserting screws for ridge expansion is a successful and predictable technique for implant placement in narrow alveolar bone.

ABSTRACT
Implants are typically placed after performing ridge expansion by inserting screws of gradually increasing thickness and good clinical outcomes are often obtained. We placed 11 implants in 6 patients, and one implant failed during osseointegration but it was replaced immediately after removal and successful prosthetic treatments were completed. During these surgeries, buccal cortical plate complete fractures do not occur. Inserting screws for ridge expansion is a successful and predictable technique for implant placement in narrow alveolar bone.

Mentions: A 31-year-old male patient with a history of right unilateral cleft lip and palate presented to our clinic with a missing right maxillary lateral incisor and alveolar bone loss. Together with orthodontic therapy, a treatment plan was developed that included a symphysis bone graft, oronasal fistula closure surgery, and implant placement. The first implant surgery was performed after a 6-month healing period following the bone graft. To secure an adequate view, a full thickness flap was created. The bone height was sufficient for implant placement and the buccolingual width was approximately 3 mm. Using SplitMaster expanding screws, a 4-mm ridge expansion was performed; subsequently, an implant that was 3.5 mm in diameter and 11 mm in length was placed. To prevent buccal bone fracture, expanding screws were carefully handled with a hand ratchet. On the buccal side, a 2-mm implant thread was exposed, so GBR with xenogeneic bones (Biocera; Osscotec, Cheonan, Korea) and barrier membranes (Bioarm; ACE Surgical Supply, Brockton, MA, USA) was performed in the exposed area. After a 4-month healing period, the second surgery to maintain the buccal volume was performed through creating a labial pouch and grafting the Biocera. After 3 months of orthodontic treatment for regaining the space of implant prosthesis, a provisional restoration was placed. After the orthodontic treatment was finished (nine months after the implant surgery), the implant was restored with an all-ceramic crown supported by zirconia abutment post.(Figs. 1,2,3,4,5,6)
