  • Maxillary implant-supported overdentures opposed by (partial) natural dentitions: a 5-year prospective case series study.
    Journal of Oral Rehabilitation, 2017
    Co-Authors: G. C. Boven, J. W. A. Slot, Gerry M. Raghoebar, Arjan Vissink, Henny J. A. Meijer
    Abstract:

    The aim of this study was to assess the 5-year treatment outcome of maxillary implant-retained overdentures opposed by natural antagonistic teeth. Fifty consecutive patients received maxillary overdentures supported by six dental implants. Implants were placed in the anterior region, if enough bone was present (n = 25 patients) Implant were placed in the posterior region if implant placement in the anterior region was not possible (n = 25 patients). Variables assessed included survival of implants, condition of hard and soft peri-implant tissues and patients' satisfaction. The five-year implant survival rate was 97·0% and 99·3%, and mean radiographic bone loss was 0·23 and 0·69 mm in the anterior and posterior group, respectively. Median scores for plaque, calculus, Gingiva, Bleeding and mean scores for pocket probing depth were low and stayed low. Patients' satisfaction after treatment was high in both groups. Within the limits of this 5-year study, it is concluded that six dental implants (placed in the anterior or posterior region) connected with a bar and opposed to natural antagonistic teeth result in acceptable results for clinical parameters and good outcomes for marginal bone level changes and patient satisfaction.

  • Single Restorations in the Resorbed Posterior Mandible Supported by 6-mm Implants: A 1-Year Prospective Case Series Study.
    Clinical implant dentistry and related research, 2014
    Co-Authors: Felix Guljé, Gerry M. Raghoebar, Arjan Vissink, Henny J. A. Meijer
    Abstract:

    The aim of this prospective case series study was to assess the clinical performance of single restorations in the posterior mandible supported by 6-mm implants. Twenty-one consecutive patients with one or more missing premolars or molars in the posterior mandible and with an estimated bone height of 8 mm between the top of the ridge and alveolar nerve were included. Each patient was to receive one or more 6-mm implants (OsseoSpeed 4.0 S, Astra Tech Implant System, Dentsply Implants, Mölndal, Sweden) without any grafting. After a 3-month osseointegration period, the implants were restored with custom-made titanium abutments (Atlantis abutment, Dentsply Implants) and cemented zirconia-based porcelain crowns. Clinical and radiographic examinations were performed at placement of the restoration and 12 months thereafter. Next to this, patients' satisfaction was scored before treatment and after 12 months with the restoration in function. Implant survival was 100%. From loading to the 12-month follow-up, mean marginal bone loss was 0.14 mm (SD: 0.4). Mean scores for plaque, calculus, Gingiva, Bleeding, and pocket probing depth were low. Patients' satisfaction was high. One-year follow-up data revealed that 6-mm dental implants inserted in the resorbed posterior mandible provide a solid basis for single tooth restoration. © 2014 Wiley Periodicals, Inc.

  • Maxillary Overdentures Supported by Anteriorly or Posteriorly Placed Implants Opposed by a Natural Dentition in the Mandible: A 1‐Year Prospective Case Series Study
    Clinical Implant Dentistry and Related Research, 2012
    Co-Authors: Wim Slot, Gerry M. Raghoebar, Arjan Vissink, Henny J. A. Meijer
    Abstract:

    Background: For maxillary overdenture therapy, treatment guidelines are missing. There is a need for longitudinal studies. Purpose: The purpose of this 1-year prospective case series study was to assess the treatment outcome of maxillary overdentures supported by six dental implants opposed by natural antagonistic teeth in the mandible. Materials and Methods: Fifty patients were treated with a maxillary overdenture supported by six dental implants, either placed in the anterior region (n=25 patients) or in the posterior region (n=25 patients). Items of evaluation were the following: survival of implants, condition of hard and soft peri-implant tissues, and patients' satisfaction. Results: One-year implant survival rate was 98% in the anterior group and 99.3% in the posterior group. Mean radiographic bone loss in the anterior and posterior groups after 1 year of loading was 0.22 and 0.50mm, respectively. Mean scores for plaque, calculus, Gingiva, Bleeding, and pocket probing depth were low, and patients' satisfaction was high, with no differences between the groups. Conclusion: Six dental implants placed in either the anterior region or the posterior region of the edentulous maxilla, connected with a bar, and opposed by antagonistic teeth in the mandible supply a proper base for the support of an overdenture.

  • Mandibular overdentures supported by 6-mm dental implants: a 1-year prospective cohort study.

    Co-Authors: Felix Guljé, Gerry M. Raghoebar, Arjan Vissink, Jan-willem P Ter Meulen, Henny J. A. Meijer
    Abstract:

    The extremely resorbed edentulous mandible, with a bone height of 8 mm or less, is still a challenge in implant dentistry. Recently, dental implants of 6 mm in length have been developed. The purpose of this 1-year prospective cohort study was to evaluate treatment outcome of mandibular overdentures supported by four 6-mm dental implants. Twelve edentulous patients with a mandibular height between 6 and 8 mm participated. The patients were treated with an overdenture supported by four 6-mm OsseoSpeed dental implants (Astra Tech AB, Mölndal, Sweden). Clinical and radiographic parameters were evaluated 1 year after completion of the prosthetic treatment. Patients' satisfaction was scored before implant surgery and 1 year after prosthetic treatment. One-year implant survival rate was 96% (two implants were lost). One patient had a fracture of the mandible in the region of one of the implants 3 weeks after implant surgery. Mean scores for plaque, calculus, Gingiva, Bleeding, and pocket probing depth were low. Patients' satisfaction was high. One-year follow-up data revealed that four 6-mm dental implants inserted in an extremely resorbed edentulous mandible provided a solid basis for a bar-retained overdenture. © 2011 Wiley Periodicals, Inc.

  • The influence of Gingival dimensions on Bleeding upon probing in young adults with plaque-induced gingivitis
    Clinical Oral Investigations, 2002
    Co-Authors: H P Muller, Achim Heinecke
    Abstract:

    In both cross-sectional and longitudinal studies of young adults with plaque-induced gingivitis it has been observed that Bleeding upon probing is only weakly associated with supraGingival plaque. It has been speculated that Gingival Bleeding may be influenced by several independent factors other than plaque. Great intra- and interindividual variation of Gingival thickness and width has been reported. Based on respective observations, the existence of different Gingival phenotypes has been suggested. The aim of the present study was to investigate the possible influence of Gingival thickness and width on Bleeding on probing. Forty young adults with mild, plaque-induced gingivitis, 24 non-smokers and 16 smokers, participated in this cross-sectional study. In addition to periodontal probing depth, clinical attachment loss, width of Gingiva, Bleeding on probing, and presence of plaque, Gingival thickness was measured with an ultrasonic device. Multivariable models were separately calculated for buccal, mandibular lingual, and palatal surfaces and generally adjusted for tooth type. Generalised Estimation Equation methodology was employed in order to adjust for correlated observations. Plaque was significantly associated with Bleeding upon probing only at buccal sites (odds ratio 1.80, 95% confidence interval 1.19–2.72) An influence of similar magnitude was identified for smoking (odds ratio 1.76; 1.07–2.89). At lingual sites in the mandible, Bleeding was influenced by smoking (odds ratio 2.25; 1.18–4.25) and Gingival thickness (odds ratio for thick Gingiva >1 mm of 1.93; 1.02–3.65), but not plaque. At palatal sites, only periodontal probing depth had an influence (odds ratio 1.89; 1.25–2.84). It was concluded that, apart from supraGingival plaque, smoking was an independent risk factor for Gingival Bleeding on probing. Thin and vulnerable Gingiva of insufficient width was not more likely to bleed after probing than thicker tissue.
