AB  - OBJECTIVES: The purpose of this cone beam computed tomography (CBCT) study was to 
      describe facial alveolar bone alterations and gray value (GV) changes around 
      implants in aesthetic anterior maxilla with simultaneous guided bone regeneration 
      (GBR) and to investigate potential influence of factors related to vertical 
      alveolar bone stability, such as particle sizes of the deproteinized bovine bone 
      mineral (DBBM) used. MATERIALS AND METHODS: A retrospective study design was 
      adopted. Four facio-palatal cross-sectional CBCT images of 166 implants from 124 
      patients who had maxillary anterior implants were obtained. Measurements of the 
      vertical facial alveolar bone level (VFBL), horizontal facial alveolar bone 
      thickness (HFBT), and GV were identified of 1-3 years. Then, correlation 
      coefficients for those parameters were calculated. Finally, linear mixed models 
      were established to investigate potential factors influencing vertical alveolar 
      bone resorption. RESULTS: Facial alveolar bone underwent fast bone modeling and 
      remodeling during the first 6 months, with decreases of 1.00 +/- 1.19 and 
      0.74 +/- 0.86 mm in VFBL and HFBT in implant shoulder, respectively, and there was 
      positive and significant correlation between the alterations in VFBL and HFBT1 
      (r(s)  = .516, p = .000). Linear mixed models identified particle size of DBBM as 
      a critical factor associated with vertical bone resorption (p = .000). The GV 
      gradually increased during the follow-up period. CONCLUSIONS: Rapid and 
      unavoidable peri-implant bone resorption usually happened during the first 
      6 months after implant placement. GBR is a predictable treatment for maxillary 
      anterior implants, since GV has an increasing trend. Large bone particles of DBBM 
      help maintain vertical alveolar bone stability.
