Abstract

INTRODUCTION: Reduced alveolar bone in posterior arches is often a complication for regular dental implant placement, which leads to a
longer, more complicated and unpredictable bone grafting procedures or nerve repositioning surgeries.
OBJECTIVES: : In this clinical case series, placing 4-mm long Global D implants supporting a fixed dental prosthesis in atrophic resorbed
posterior, arches were evaluated for 6 months.
MATERIALS AND METHODS: In nineteen dental arches, 43 dental implants were placed and a screw retained Fixed dental prostheses
were attached to two or three dental implants. All implants were placed in adequate amount of bone. No bone grafting procedures were
implemented. A minimum torque of 25 Ncm was used to place the dental implants.
RESULTS Forty-three dental implants were inserted. Three dental implants failed before loading. 17 Fixed dental prostheses were delivered.
One patient didn’t show up for follow up and dropped out of the study. Forty-one implants were eligible for examination and follow up. At 6
month-post–insertion, the survival rate reached 92.7%. No patients suffered from any complications or side effects after implant surgeries. The
mean change in the marginal bone loss around implant was found to be 0.22 mm with SD of 0.43 mm p<0.01.
CONCLUSIONS: This study shows that 4 mm trans-mucosal dental implants with roughed sand blasted large grit acid etched surfaces can
be safely used to support fixed partial prosthesis in atrophic posterior ridges. Further and longer follow up is needed for these types of implants.
KEYWORDS: bone loss, crown-implant ratio, jaw bone atrophy, short implants.
