Evaluation of Dental Implant Stability Regarding All-on-4 Concept Utilizing Two Different Angles

Background: The “All-on-4” technique using 4 implants that has gained popularity in full arch edentulismcases recent years was presented as a modern implant-denture rehabilitation by Malo inLisbon, Portugal, for the first time 2003 and all-on-four concept began to be used atrophic fullarch mandibular maxilla 2005 emerged.Aim: evaluation of dental implant stability relation All-on-4 concept.Materials Methods: This clinical prospective comparative study organized from February 2019to March 2020 College Dentistry Teaching Hospital, Department Oral & Maxillofacial Surgery/Dental Implant Unit/University Baghdad. A total 15 Iraqi patients aged 41-73 years, 9 males 6females were enrolled this receiving 80 Dental (All-on-4 concept). Patients classified intotwo groups, group with 2 anterior axial posterior angulation 17°) B(All-on-4 30°). For both, surgical site dentalimplant examined hard soft tissues clinically radiographically utilizing OPG CBCT.Results: mean ISQ values obtained at each point implant,axially placed angled demonstrated significant increase (P = 0.000, 0.031 0.004)respectively different times. There angledimplants concerning 0.001 P =0.002) respectively than females. Significant correlationbetween regions three times periods. difference inangled between intervals 0.001) >50y. Success implants95.24%.Conclusion: All-on-4–style full-arch procedures have one highest success rates ofdental treatment; had effect mandible comparison maxilla.There irrelevant analysis result statical withdifferent variables.
