implant stability is the first requirement for implant success. the aim is to assess whether different implant site preparation technique may impact the value of the primary stability.

Impianti stability represents one of the most fundamental issue for implant success. Different techniques of implant site preparation are available such as twist drill, osteotome, piezosurgery and lastly, osseodensification. Due to their different approach an biological rationale, piezosurgery and osseodensification might show diverse impact on implant first and secondary stability, therefore the aim of the present study was the assessment of primary and secondary stability changes of values between implant sites prepared with piezoelectric bone surgery and with specific osseodensification drills.

Patients with bilateral single maxillary edentulism will randomly receive implant site preparation with piezoelectric approach or with osseodensification drills. standardized implants will be therefore inserted and primary stability will be assessed at the time of implant insertion and during the subsequent timepoints.

Inclusion Criteria:

• bilateral single maxillary edentulism

Exclusion Criteria:

• smoking habit
• history of periodontal disease
• uncontrolled diabetes
• pregnancy or breastfeeding
• head and neck radiotherapy or chemotherapy
• bone antiresorptive therapy
• coagulopaties
