For analysis of clinical efficacy, data from two slightly different analysis populations will be used, i.e. the Per Protocol (PP) and the All Patients Treated (APT) populations. The primary objective is to determine the alterations in the buccal and palatal aspects of the size of the defect dimensions at implant placement and after healing. Results will be presented by appropriate descriptive and inferential statistics. Continuous variables will be presented by means of number of observations (N), minimum (min), median, maximum (max), mean and standard deviation (std). Discrete variables will be presented by frequency and percentage.
