Edentulous area of at least one tooth missed in the posterior sextant of maxilla; which is considered to be treated with implant supported fixed prosthesis; available bone height of at least 6 mm and less than 10 mm below the maxillary sinus in the area planned for implant insertion, as observed in CBCT radiograph; available bone width of at least 6 mm in the area planned for implant insertion as observed in CBCT radiograph; sinus augmentation not planned, because of medical reasons or patient's unwillingness; and patient's willing for cooperation with the study.
Exclusion criteria:
Active periodontal disease (Probing pocket depth >=4 mm with bleeding on probing); full mouth plaque score >20% at time of implant placement; full mouth bleeding score >20% at time of implant placement; smoking >10 cigarettes/day; systemic disease or conditions which influence bone metabolism; and bruxism or clenching.

- Primary Outcome Measures
Name Time Method Marginal bone level changes. Timepoint: At implant placement, prosthesis delivery and 6 months later. Method of measurement: a standardized radiograph is taken For evaluation of marginal bone level, CBCT viewer software is used for assessing the radiographs. the distance between bone to implant contact and platform of each implant, at mesial and distal of implants were calculated at each intervals.
- Secondary Outcome Measures
Name Time Method Probing depth. Timepoint: At prosthesis delivery and 6 months later. Method of measurement: O’ Michigan, Williams marking probe.;Bleeding on probing. Timepoint: At prosthesis delivery and 6 months later. Method of measurement: Bleeding on probing with O’ Michigan, Williams marking, which may happen till 30 seconds later.;Implant survival rate. Timepoint: At prosthesis delivery and 6 months later. Method of measurement: Percentage of remained implants in oral cavity at the end of study.
