The purpose of this study was to demonstrate clinical outcomes of sandblasted, large-grit, acid-etched (SLA)-surfaced tapered implants when early loaded in partially edentulous spaces in the maxilla. SLA-surfaced implants were placed in participants in the maxillary posterior edentulous area. At the time of definitive restoration, participants were allocated either to group 1 (3-month loading group) or group 2 (6-month loading group). A total of 36 participants (18 people [35 implants] in group 1 and 18 [33 implants] in group 2) were analyzed. Clinical outcomes, including survival rate and peri-implant parameters such as marginal bone loss were measured 1 year after loading. The survival rate was 97.0% in group 1 and 100% in group 2. Marginal bone loss was 0.22 (+/-) 0.34 mm in group 1 and 0.17 +/- 0.25 mm in group 2 at 1 year after loading (P = .488). There were no significant differences between groups in keratinized mucosa! width (P = .206), Plaque Index (P = .677), or Gingival Index (P = .558). With adequate remaining bone height and primary implant stability achieved, the 3-month early loading of SLA-surface tapered implants may be a viable choice when restoring posterior maxillary edentulous areas.
