Eligibility

Sex/Gender
All

Inclusion criteria

Inclusion criteria: 1. Complete mandibular edentulism, with functional and aesthetic problems related to the presence of a complete, removable conventional denture (i.e. lack of stability of the complete denture, discomfort during function and aesthetic embarrassment) 2. Irreparably compromised mandibular dentition, due to advanced periodontal disease or destructive/massive tooth decay, that made the residual dental elements unrestorable 3. Sufficient bone volume (bone height x width) to allow for the placement of implants of at least 8 mm in length and 3.0 mm in diameter 4. Will to restore the masticatory function with a fixed mandibular prosthesis supported by dental implants 5. Ability to understand and sign an informed consent form for implant treatment.

Exclusion criteria

Exclusion criteria: 1. General medical conditions/systemic diseases that represented an absolute contraindication to surgical and implant treatment, such as severely immunocompromised patients or severely uncompensated diabetics, patients receiving radiotherapy to the head and neck area or chemotherapy, patients receiving amino-bisphosphonates intravenously and/or orally 2. Psychiatric disorders 3. Addicted to alcohol or drugs 4. Needed bone augmentation procedures with autogenous bone or other bone substitutes, to allow for proper implant insertion 5. Previously undergone major regenerative bone surgery, preliminary to the placement of dental implants

Design outcomes

Primary

MeasureTime frame
Implant survival, i.e. the clinical condition in which the implants are still in function in the patients' mouth, at the end of the 2-year follow-up period

Secondary

MeasureTime frame
Prosthetic success, i.e. the clinical condition in which no adverse events or complications (such as fractures/alterations of the resin superstructure and of the intraorally welded titanium framework) occur at the prosthesis level, assessed at the end of the 2-year follow-up period
