An interventional study of Short implant placement and Bone regeneration with longer implants in Implant Complication and Bone Resorption, sponsored by University of Valencia. Completed at 1 site in Spain. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-07-13.
Sponsored by University of Valencia · Not applicable, Interventional, and Treatment
A study designed as a randomized controlled trial of parallel group design will be conducted at the Dental clinic of the University of Valencia to compare, considering different parameters, the rehabilitation with dental implants of atrophic posterior mandibles or maxillae using short implants or longer implants with vertical bone regeneration with GBR.
The hypothesis of the study is that both treatment options will be successful to rehabilitate atrophic posterior mandibles or maxillae. Moreover, more surgical complications will be encountered in the bone regeneration group.

Exclusion Criteria:
2 or 3 implant 4-5 mm length and 4 mm diameter (Syra Short, Sweden \& Martina, Padua, Italy) will be positioned. The healing cap will be immediately connected and a vycril suture will be done after soft tissue reflection.
Procedure: Short implant placement
A horizontal and vertical regeneration following GBR technique will be performed using not-resorbable PTFE titanium reinforced membrane (Cytoplast Osteogenics, US) fixed by titanium pins or miniscrews to ensure the perfect stability (Pro-fix, Cytoplast Osteogenics, US). The graft will be composed half autogenous bone harvested with a scraper (Meta, Firenze, Italy) by the same surgical site or by a second tunnel site in the mandibular ramus and half deproteinized bovine bone (Bio Oss Geislicht Pharma, Switzerland). The mucosal flaps will be sutured in a double layer with horizontal mattress and single gore-tex sutures (Cytoplast PTFE sutures 3.0, Cytoplast Osteogenics, US). 2 or 3 implant from 10 to 13 mm length putting the implant platform 2 or 3 mm apical to CEJ of the adjacent tooth will be inserted.
Procedure: Bone regeneration with longer implants
Ten patients will be randomly selected for the short implants option, 2 or 3 implant 4-5 mm length and 4 mm diameter (Syra Short, Sweden \& Martina, Padua, Italy) will be positioned. The healing cap will be immediately connected and a vycril suture will be done after soft tissue reflection. After three months an acrylic screw-retained bridge will be delivered. After further three months, a definitive restauration with a metal ceramic bridge will be seated.
Ten patients will be randomly assigned to the regenerative group, 2 or 3 implant from 10 to 13 mm length intentionally exposed putting the implant platform 2 or 3 mm apical to CEJ of the adjacent tooth will be inserted. A horizontal and vertical regeneration following GBR technique will be performed using not-resorbable PTFE titanium reinforced membrane (Cytoplast Osteogenics, US) fixed by titanium pins or miniscrews to ensure the perfect stability (Pro-fix, Cytoplast Osteogenics, US).
