Short‐term clinical results of Nobel Direct implants: a retrospective multicentre analysis

Abstract

This short-term retrospective analysis showed a poor clinical outcome of Nobel Direct implants. Extensive marginal bone loss (>3 mm) was found around more than 1/3 of the implants evaluated. Less resorption and no failures were experienced when implants were allowed to heal from 6 weeks to 6 months before occlusal loading. Within the limitations of the present study design, data indicate that immediate loading, the use of this implant for multi-unit constructions and flapless surgery are risk factors for failure of Nobel Direct implants.

Dental implants inserted in fresh extraction sockets versus healed sites: A systematic review and meta-analysis

“…Five RCTs, 2,14-17 twenty-six CCTs, 4,7,8, and forty-two retrospective analyses 3,5,6,9, were included in the meta-analysis. Sixteen studies 5,14,18,19,23,27,33,34,39,45,54,57,59,60,63,77 were multicenter.…”

“…Patients were submitted to grafting procedures at the implant site in thirty-five studies. 2,9,[14][15][16]18,20,21,23,26,29,33,36,37,39,41,42,44,45,53,57,[60][61][62][63][64][67][68][69][72][73][74][76][77][78] Implants were inserted exclusively in maxillae in seventeen studies 2,16,20,27,31,[33][34][35]37,38,52,53,59,66,71,72,74 and in mandibles in six stu...…”

Photoelastic Stress Analysis in Prosthetic Implants of Different Diameters: Mini, Narrow, Standard or Wide

“…Besides these limitations, the longevity of such mini-and narrowdiameter implants has been proved by several clinical studies [1][2][3][4][18][19][20] in which the survival rate of these implants are similar to those observed with standard-diameter implants. Recently, Geckili et al, [1] showed the overall implant success rate after 5y of loading time (98.74%) indicating that narrow implants can be successfully used to support fixed or removable prosthesis.…”

“…It might be explained by the implant angulation that generates greater lever arm during loading application and promote higher torque around the implant [19].…”

Management of Missing Second Premolar with Single-Tooth Implant using Flapless Surgery

“…13 This technique has numerous advantages, including preservation of circulation, soft tissue architecture, and hard tissue volume at the site; decreased surgical time; improved patient comfort; and accelerated recuperation. It also allows the patient to resume normal oral hygiene procedures immediately after the surgery.…”
