Scalloped Dental Implants: A Retrospective Analysis of Radiographic and Clinical Outcomes of 17 NobelPerfect^TM Implants in 6 Patients

Abstract

This chart review of 17 scalloped implants, followed for 18 months, determined that the scalloped implant design resulted in bone loss that was more severe than that associated with properly placed conventional dental implants. Further, the design showed no evidence of exceptional capacity to increase or maintain soft tissue height.

Treatment outcome of two adjacent implant crowns with different implant platform designs in the aesthetic zone: a 1-year randomized clinical trial

“…The results of this study are also comparable with the results of articles reporting on implants with the same titanium oxide surface (TiUnite) as that used in the present study (Glauser et al 2003, Vanden Bogaerde et al 2005) and implants with a scalloped platform (Kan et al 2003, Nowzari et al 2006. A comparison with articles reporting on implant survival of adjacent implants could not be made because there were no articles reporting on survival rates.…”

“…Some studies reported that the interproximal bone crest with a scalloped implant design could be preserved (McAllister 2007, Noelken et al 2007), whereas Kan et al (2007) observed that bone was not regularly maintained at the original levels around the scalloped implants. Moreover, Nowzari et al (2006) observed bone loss around the scalloped implants that was more severe than bone loss associated with properly placed flat implant designs. To date, there are no clinical prospective comparative studies in the literature, evaluating the treatment outcome of adjacent scalloped implants in the aesthetic zone.…”

Immediately Restored, Single‐Tapered Implants in the Anterior Maxilla: Prosthodontic and Aesthetic Outcomes After 1 Year

“…8,9 A variety of surgical techniques have been advocated to improve the mucosal aesthetic outcome of single implant crowns. These include, albeit controversially, parabolic implant design; [11][12][13] soft and hard tissue augmentation either prior to, concurrent with, and/or after implant placement; [14][15][16][17][18] and surgical incision techniques that preserve or create papillae. 19,20 Evidence sometimes suggests that these interventions do not improve soft tissue outcomes when compared to simple standardized surgical techniques.…”

Effects of Coronal Thread Pitch in Scalloped Implant with 2 Different Connections on Loading Stress using 3 Dimensional Finite Element Analysis

“…Scalloped implant was introduced 7 to enhance the esthetic outcome since anterior teeth have high proximal and low mid-facial gingival soft tissue that reflects the underlying scalloping osseous architecture 8 . However, few studies available on first generation scalloped implant design showed that marginal bone loss was significantly greater than conventional flat-top implant [9][10][11] , thus negating the theoretical benefits of scalloped implant and adversely affecting possible clinical outcomes.…”
