Prosthetic Modality and MBL

The present study will test the effect of different prosthetic modalities on conical and internal hex connection implants, assessing the radiographic MBL changes after one year. Consecutive patients fulfilling inclusion/exclusion criteria will enter the study. Once the implant is inserted, patients will be divided into three groups according to the time if their inclusion in the study. Study groups (20 patients per group): 1. Group 1: Placing Lance Conical implant with a healing abutment. Three months later, after an impression, a screw-retained restoration will be seated using a Ti-Base abutment. 2. Group 2: Placing Lance+ (Internal Hex connection) implant with a healing abutment. Three months later, after an impression, a screw-retained restoration will be seated using a Ti-Base abutment. 3. Group 3: Placing Lance Conical implant together with Connect Abutment (tightened to 30 Ncm) with a Connect healing cap ("one time one abutment"). Screw retained restoration after 3 months. Consecutive inclusion of patients - 1st- group 1, 2nd - group 2, 3rd - group 3 and vice versa. Primary outcome variable: bone level changes 12 months post-loading
