The design features of the scalloped implant include hard and soft tissue apposition areas, which are parallel to each other and mirror the cementoenamel junction. The hard tissue surface area is intended for osseointegration. The soft tissue surface area is meant to support the connective tissue zone and to provide a space for the subgingival margin of the restoration. Current literature on the clinical performance of the scalloped dental implant is limited.<\/jats:p><jats:p><jats:bold>Purpose:\u2002<\/jats:bold> The aim of this study was to evaluate whether the scalloped dental implant maintains interproximal bone and the overlying soft tissue.<\/jats:p><jats:p><jats:bold>Materials and Methods:\u2002<\/jats:bold> Radiographs for six patients (mean age 40.5 years) treated with 17 implants (NobelPerfect) were reviewed for an 18\u2010month follow\u2010up evaluation of bone response. Orthodontic movement and\/or autogenous bone augmentation had been provided to obtain the best possible soft and hard tissue dimensions prior to implant placement. A surgical guide was used for an optimal implant placement. No surgical flap was reflected, and implants were placed a minimum of 2\u2003mm and a maximum of 3\u2003mm apical (midbuccally) to the most apical portion of the surgical guide. Final optimal rotational alignment was achieved in all cases by not exceeding 45\u2003Ncm. Implants were immediately restored with provisional crowns. Photographic documentation provided the basis for analysis of papillary response. Radiographic change in the interproximal bone level was obtained by computer analysis (<jats:italic>ImageJ<\/jats:italic> for Windows, National Institutes of Health, Bethesda, MD) by measuring the distance from the interproximal shoulder of the scalloped implant to the crest of the bone.<\/jats:p><jats:p><jats:bold>Results:\u2002<\/jats:bold> When the scalloped implants were placed adjacent to existing natural dentition, the average bone level at placement and at 6, 12, and 18 months was \u22121.7, \u22123.5, \u22123.8, and \u22123.9\u2003mm, respectively, compared with \u22121.0, \u22123.6, \u22124.3, and \u22124.4\u2003mm respectively, when placed adjacent to other scalloped implants. Papillae formation exhibited no differences from the configuration that typically results after placement of conventional dental implants. Moreover, bone loss around the scalloped implants was notably greater than that expected after traditional implant placement.<\/jats:p><jats:p><jats:bold>Conclusion:\u2002<\/jats:bold> 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.<\/jats:p>","DOI":"10.2310\/j.6480.2005.00034.x","type":"journal-article","created":{"date-parts":[[2010,11,2]],"date-time":"2010-11-02T17:57:01Z","timestamp":1288720621000},"page":"1-10","source":"Crossref","is-referenced-by-count":37,"title":["Scalloped Dental Implants: A Retrospective Analysis of Radiographic and Clinical Outcomes of 17 NobelPerfect<sup>TM<\/sup> Implants in 6 Patients"],"prefix":"10.1111","volume":"8","author":[{"given":"Hessam","family":"Nowzari","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Winston","family":"Chee","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Klaus","family":"Yi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark","family":"Pak","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Woun Ho","family":"Chung","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sandra","family":"Rich","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2006,5,2]]},"reference":[{"key":"e_1_2_6_2_2","first-page":"11","article-title":"The long\u2010term efficacy of currently used dental implants: a review and proposed criteria of success","volume":"1","author":"Albrektsson T","year":"1986","journal-title":"Int J Oral Maxillofac Implants"},{"key":"e_1_2_6_3_2","first-page":"347","article-title":"Long\u2010term follow\u2010up study of osseointegrated implants in the treatment of totally edentulous jaws","volume":"5","author":"Adell R","year":"1990","journal-title":"Int J Oral Maxillofac Implants"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0300-9785(81)80077-4"},{"key":"e_1_2_6_5_2","first-page":"453","article-title":"Patient\u2010based outcomes of implant therapy: a review of the literature","volume":"11","author":"Locker ES","year":"1998","journal-title":"Int J Prosthodont"},{"key":"e_1_2_6_6_2","first-page":"335","article-title":"Esthetic outcome of implant supported single\u2010tooth replacements assessed by patient and prosthodontist","volume":"12","author":"Chang M","year":"1999","journal-title":"Int J Prosthodont"},{"key":"e_1_2_6_7_2","first-page":"326","article-title":"Regeneration of gingival papillae after single\u2010implant treatment","volume":"17","author":"Jemt T","year":"1997","journal-title":"Int J Periodontics Restorative Dent"},{"key":"e_1_2_6_8_2","first-page":"20","article-title":"Restoring the gingival contour by means of provisional resin crowns after single\u2010implant treatment","volume":"19","author":"Jemt T","year":"1999","journal-title":"Int J Periodontics Restorative Dent"},{"key":"e_1_2_6_9_2","first-page":"30","article-title":"Outcome analysis of implant restoration located in the anterior maxilla: a review of the recent literature","volume":"19","author":"Belser UC","year":"2004","journal-title":"Int J Maxillofac Implants"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.0906-6713.2002.03309.x"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.2005.00748.x"},{"key":"e_1_2_6_12_2","first-page":"473","article-title":"Concept for a biologically derived, parabolic implant design","volume":"22","author":"Holt RL","year":"2002","journal-title":"Int J Periodontics Restorative Dent"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1097\/01.ID.0000067682.95950.A2"},{"issue":"1","key":"e_1_2_6_14_2","first-page":"64","article-title":"TM esthetic scalloped implant: rationale for a new design","volume":"5","author":"NobelPerfect Wohrle PS.","year":"2003","journal-title":"Clin Implant Dent Relat Res"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.1902\/jop.1998.69.10.1124"},{"key":"e_1_2_6_16_2","doi-asserted-by":"publisher","DOI":"10.1902\/jop.1992.63.12.995"},{"key":"e_1_2_6_17_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-051X.1997.tb00189.x"},{"key":"e_1_2_6_18_2","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-0501.2001.120603.x"},{"key":"e_1_2_6_19_2","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2001.72.10.1372"},{"key":"e_1_2_6_20_2","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2000.71.9.1412"},{"key":"e_1_2_6_21_2","first-page":"427","article-title":"Esthetic rehabilitation of incisors with hard and soft tissue augmentation and NobelPerfectTM implants","volume":"7","author":"Noelken R","year":"2003","journal-title":"Dent Implantol"},{"key":"e_1_2_6_22_2","first-page":"331","article-title":"Replacement of adjacent missing anterior teeth with scalloped implants: a case report.
