Tooth-Supported Overdenture – Preventive Prosthodontics to Redeem Ridge Resorption

Abstract This case series elaborates on tooth-supported overdenture for prosthetic rehabilitation as a treatment modality in partially edentulous patients. Loss of teeth causes continuous ridge resorption and poor denture foundation affecting the success of prosthesis. Retained natural teeth act as abutments for prosthetic rehabilitation of partial edentulous arches. Tooth-supported overdenture is the mainstay of preventive prosthodontics which preserves natural teeth and/or roots. The cases describe the use of tooth-supported complete overdenture and removable partial overdenture with metal denture base to rehabilitate partially edentulous arches. The natural teeth maintain proprioception and provide additional support, stability, retention, and psychological benefit to the patient than the conventional complete denture with completely edentulous ridges.

Tooth-Supported Overdentures Revisited.

The goal of prosthodontics is to provide a functional prosthesis to restore aesthetics, functions, and masticatory efficiencies. Tooth-supported overdentures are one of the treatment options for removable dentures. This article aims to discuss the advantages and disadvantages of tooth-supported overdentures and the principles of using various overdenture attachments, including non-attachment overdentures. The common treatment options in preparing the overdenture abutment are either with or without abutment copingwith or without attachment systems, which were discussed and illustrated. A range of tooth-supported overdenture systems were addressed, from low to high financial implications and treatment complexities. The clinician can choose a system that best fits the patient's condition and expectations. This allows clinicians to decide and consider tooth-supported overdentures as a treatment option before full edentulism. A well-executed tooth-supported overdenture ensures the preservation of alveolar bone, optimizes patient satisfaction in denture treatment, and eventually improves the patient's adaptation when transitioning to complete dentures.

Single Implant-Retained Mandibular Overdentures: A Literature Review.

The absence of teeth, known as edentulism, poses considerable obstacles in prosthodontic care and greatly affects a person's well-being. Conventional complete dentures frequently lead to problems like instability and insufficient retention, especially in the lower jaw. Fortunately, the introduction of dental implants has transformed the way we approach edentulous patients, as they now offer support and enhanced retention for removable prostheses, thus revolutionizing their treatment. While a consensus exists on using two implants for retaining mandibular overdentures, the associated cost may be prohibitive for economically disadvantaged individuals. As a solution, the concept of single implant-retained mandibular overdentures has emerged, catering to individuals with limited financial resources and complete tooth loss. This review explores the efficacy and suitability of the single implant overdenture approach, along with an overview of treatment options for edentulous patients, including traditional dentures, tooth-supported overdentures, and implant-supported overdentures. The preservation of bone, improvements in functional abilities, and psychological benefits associated with overdentures are discussed. Moreover, various classifications and prosthetic options for implant overdentures, specifically for mandibular cases, are presented. This literature review aims to provide a comprehensive understanding of possible treatment options and focus on the single implant-retained mandibular overdenture approach and its implications in prosthodontic rehabilitation for edentulous patients.

Harmony in attachment: A case report of tooth-supported overdenture using locator attachment

The over-denture is a frequently employed treatment for elderly patients who have two or more remaining teeth in the arch. The presence of these remaining teeth contributes to the preservation of the alveolar ridge, provides sensory feedback, and enhances the stability and retention of the denture. This is in contrast to conventional complete dentures, where stability and retention are typically improved by utilizing coping or attachments over the remaining portions of the teeth. The incorporation of these remaining teeth significantly enhances the overall stability and retention of the denture. This case report presents prosthetic rehabilitation of a partially dentulous mandibular arch with a tooth supported overdenture with extra coronal attachments aimed to attain normal structure and functionality.

A Root-Supported Overdenture: An Approach to Preventive Prosthodontics

The use of residual teeth to support an attachment-retained overdenture is an alternative therapy to extractions and complete removable denture, particularly for the mandibular arch. Overdenture offers several advantages, including maintenance of the alveolar ridge and proprioception. Retention and stability are also enhanced by means of attachment systems, which improves schwing efficiency and better psychological integration of the prosthesis. This article describes, through a clinical case, the fabrication and interest of a tooth-supported overdenture using two axial attachments.

Rehabilitation with Tooth-supported Overdenture Incorporating Matrix Attachment System in a Teenager and a Hexagenerian: A Clinical Technique

The aim of this study is to evaluate the improvement in masticatory efficiency and retention of tooth-supported overdenture using customized copings over abutment teeth with a silicone-based matrix attachment system present an alternative to prefabricated precision attachments. Saving mutilated teeth and using them for overdenture has been a good alternative to the conventional dentures. Using customized attachments improved the retention of the prosthesis. The new material which has been widely used for implant-supported overdentures has been used with tooth-supported overdentures for improved function and comfort. A 14-year-old patient reported with difficulty in eating due to decayed teeth. Customized copings were fabricated on endodontically treated teeth 13, 23, 33, and 43 and overlay prosthesis was conventionally fabricated. The intaglio surfaces corresponding to the abutments were lined with Multisil primer and retention. Sil 600 and the patient were asked to bite to aid the removal of excess material. A 65-year-old patient complained of missing teeth and inability to chew. A thimble-shaped coping was fabricated on endodontically treated teeth 33, 34, and 43. Subsequent procedures were similar to the aforementioned case. The use of polyvinyl siloxane-based resilient liners has proven to be able to provide clinically satisfactory retention in patients with compromised manual dexterity. Significant results, in retention with the use of two different coping designs and single-matrix system, masticatory efficiency, and esthetics have been observed and economical alternative to the use of expensive attachments.

Tooth-supported overdenture vs stud retained overdenture: a case report

Overdenture can preserve alveolar bone while providing support and stability to the prosthesis. This case report describes a treatment of a tooth-supported partial overdenture for the upper and lower stud retained overdenture. This method provides an alternative solution to the conventional partial denture and implant retained overdenture. This treatment is a simple and cost-effective, which provides the patient with a highly retentive, stable denture with improved masticatory performance.

Tooth-Supported Overdenture Retained with Ball Attachments and Custom-made Coping: A Case Report


 Introduction: Tooth-supported overdentures is a simple and cost-efficient modality that helps preserve bone. This concept is completely supported by DeVan’s maxim: “Perpetual preservation of what is left is more important than the exact replacement of what is lost.” The preserved tooth structure beneath the denture base prevents alveolar ridge resorption, enhances proprioception, and improves denture support and stability. Additionally, using copings on the remaining teeth improves the denture’s retention.
 Case Report: A 49-year-old female patient reported having the chief complaint of difficulty in chewing food due to missing teeth in the upper and lower arch. An intraoral examination revealed a partially edentulous maxillary arch with denture-induced stomatitis as the patient had a faulty maxillary removable partial denture for five years. The mandibular arch was also partially edentulous, and only mandibular left second premolar and right first and second premolar were present. The patient was advised to stop using maxillary removable partial denture (RPD) altogether and was given an antifungal tablet as well as a multivitamin tab and topical clotrimazole. This case report describes prosthodontic rehabilitation of a mandibular’s partially edentulous arch with tooth-supported overdenture using ball attachments and custom-made coping.
 Conclusion: For edentulous patients with few remaining teeth, a mandibular tooth-supported overdenture is one of the best and most practical, feasible, and comfortable treatment alternatives. The patient was satisfied with the treatment outcome.

A case report on tooth-supported overdenture with an extra-radicular attachment

Introduction: Over-dentures are the most commonly used treatment for elderly patients who still have two or more teeth in their arch. When using coping or attachment over the remaining part of the tooth, the root of the remaining teeth preserves the alveolar ridge, provides sensory sense, and improves the stability and retention of the denture when compared to conventional complete dentures. This report presents a case of rehabilitation of partially edentulous 55 year old male patient who had a chief complaint of poor esthetics and difficulty in chewing due to missing teeth.Method: Considering the age of the patient and the cost involved, implant supported prosthesis was ruled out as a treatment option for the patient. A tooth supported overdenture was chosen as a favorable treatment option since it overcomes many of the problems posed by conventional complete dentures. Extra- radicular attachments were used to improve the retention and stability.Result: Evaluation of occlusion, esthetics, phonetics and comfort after 24 hours, 1 week and 1 month, 6 months of treatment showed that the patient was satisfied with the prosthesis.Conclusion: The denture's stability and retention are improved on using tooth-supported over-denture retained with extra-radicular attachment. This treatment option provides improved chewing efficiency, patient comfort and reduce the residual ridge resorption.Clinical Significance: Prosthetic rehabilitation by means of tooth supported overdenture maintains the integrity of residual alveolar ridge, provides more bone support and helps in preservation of sensory input by facilitating enhanced occlusal awareness, biting force and neuromuscular control from the periodontal tissue.

Conservative approaches in prosthodontic management of cleft lip and palate patients

The goals of prosthodontic management of patients with cleft lip and palate (CLP) are the restoration of esthetics and improvement of speech and occlusion. Deficiency of bone volume, soft-tissue excess, or presence of oronasal fistula complicates the treatment planning. Though dental implants present a viable treatment option to replace missing teeth in the cleft region, the need for bone augmentation and surgical morbidity limits its application in some patients. A combination of fixed dental prosthesis, resin bonded bridges, removable prosthesis, and overdentures allows conservative management of such patients without causing further morbidity. This clinical report illustrates two patients with CLP managed with a resin-bonded Maryland Bridge and a tooth-supported overdenture.

Partial anodontia with macroglossia: An esthetic and functional challenge for a prosthodontist

Partial anodontia is considered as one of the most crucial developmental anomalies in the dentofacial region. In the permanent dentition, the prevalence rate of true partial exodontia is 3.5%–6.5%. The clinical situation in relation to this abnormality is very distressing for the patient; at the same time, it is a strenuous challenge for the clinician to bring it to the normal function and esthetics. This case report discusses the prosthodontic rehabilitation of a young girl with the partial anodontia that was treated with the tooth-supported over-denture using Ceka Preci precision attachments. The ultimate aim was to rehabilitate her prosthodontically to uplift her mental and esthetic status.

Conventional tooth supported overdenture with copings –Can it ever be overlooked?

Over denture is a one of the recommended treatment modality for aged patients with few remaining teeth with severely resorbed ridges. Root stumps under the denture base preserve further resorption of alveolar ridge which provides sensory feedback and improves the stability of the dentures. Moreover, the use of copings (short/long) and attachments on the remaining teeth after enododontic therapy enhances the retention of the denture. Success for the treatment depends on strategic selection of teeth. The present case report demonstrates the successful preservation of few remaining teeth to support tooth-retained overdenture. This treatment modality was selected considering the favorable inter ridge distance and economical status of the patient rather than complete extractions followed by complete denture or implant supported overdenture.

Evaluation of telescopic tooth-supported overdentures regarding surrounding supporting structures case study

IntroductionOverdenture according to the glossary of prosthodontic is removable dental prosthesis that covers and rests on one or more remaining natural teeth, the roots of natural teeth, and/or dental implants1. Root-supported overdentures have been fabricated to correct periodontal and/or occlusal collapse, some teeth are maintained to support or retain the prosthesis and therefore, maximizing prosthesis stability, besides preserving proprioception of the periodontal ligament and reducing bone loss2. Telescopic copings have been used for several years in oral rehabilitation of patients with advanced periodontal disease. Patients with periodontal disease undergoing prosthetic reconstruction often present with teeth with minimal supportive tissue and increased tooth mobility. Therefore, it is extremely important for the prosthesis not to cause periodontal destruction or worsen an existing periodontal condition. ObjectiveThe aim of this study was an evaluation of telescopic mandibular tooth-supported overdentures regarding surrounding supporting structures both clinically and radiographically. Materials and methodA 55 years old male patient with few remaining natural teeth was selected from the outpatient clinic in Umm-Alqura university faculty of dentistry. As remaining teeth were periodontally compromised, and low the number of teeth in lower arch for a constructed removable partial denture, It was concluded that mandibular canines and premolars can serve as abutments for an overdenture. Analysis of the mounted cast was made to ensure sufficient space for construct overdenture. The treatment plan was divided into three phases: Phase 1: Caries excavation, Phase 2: Intentional endodontic treatment, Phase 3: Prosthodontic rehabilitation. RESULT: According to the clinical and radiographical measurements in the delivery visit and after one year from the treatment, we concluded that there is no obvious difference. ConclusionTelescopic overdentures have better retention and stability as compared to complete dentures, they improve the chewing efficiency and the comfort of the patient and they also decrease the alveolar bone resorption. According to the result, in this case, the attachment level in the patient mouth and bone change in height or width by cone beam computed tomography (CBCT), and the patient was satisfied from the denture and grateful.

Overdentures borne on less than four abutments with telescopic crowns: 5-year results of a retrospective clinical study.

Retrospective evaluation of the clinical performance of tooth-supported overdentures retained by resilient telescopic crowns with occlusal clearance fit (ODRTC) in severely reduced dentition (1-3 remaining teeth). A total of 313 ODRTCs were inserted in an undergraduate prosthodontic program (University Medical Center, Goettingen, Germany) between 2000 und 2012. Data regarding 263 ODRTCs in 221 patients were reevaluated (observational period: 64.5 ± 34.8months), and time-dependent survival and success rates (Kaplan-Meier-Estimator) were calculated. The number of the abutment teeth was analyzed as an influencing factor (Cox regression model (p < 0.05)). The 5- and 8-year overdenture survival rates were 62% [CI: 0.55; 0.69] and 38% [CI: 0.30; 0.45]. The 5- and 8-year success-rates (biologically and technically event-free restorations) were 13% [CI: 0.09; 0.17] and 3% [CI: 0.01; 0.05]. On the abutment level, the 5- and 8-year survival rates were 55% [CI: 0.48; 0.62], and 34% [CI: 0.27; 0.42]. The number of abutment teeth significantly influenced the overdenture and abutment survival rates. Restorations with 1 or 2 abutments were significantly associated with an increased number of technical and biological complications (decementation of the primary crown, abutment fracture) compared to ODRTCs with 3 abutments. The survival and success rates of ODRTCs are significantly influenced by the number of abutments. For ODRTCs, reduced survival and success rates are expected, especially when only 1 or 2 abutment teeth are included.

Longitudinal Assessment of Denture Maintenance Needs in an Overdenture Population.

To evaluate the longitudinal denture maintenance needs of a tooth-supported overdenture population. This prospective cohort study was composed of patients who had received tooth-supported overdentures from 1974 to 1994 in the Department of Prosthodontics, University of Iowa. There were 272 persons with 662 abutments who fulfilled the inclusion criteria. To simplify analysis and reduce the number of confounding variables, only those participants wearing complete maxillary dentures and opposing complete mandibular overdentures supported by teeth #22 and #27 were included in this analysis. The denture maintenance needs of these participants were identified and related to age, gender, length of time wearing overdentures, number of medications, and denture-wearing habits. Descriptive statistics and bivariate analyses were used for the statistical analysis (α = 0.05). Of the 91 participants (mean age = 59.5 ± 10.1 years; 63.7% male) who fulfilled the inclusion criteria at baseline, 48.4% took 1 to 3 medications daily, and 84.6% wore their dentures day and night. The percentages of participants who needed one or more of the following denture treatments were: 91.2% denture base adjustments, 76.9% laboratory processed relines, 61.5% denture remakes, 33% laboratory remount and occlusal adjustment, 22% repaired bases, and 19.8% needed denture teeth replaced. Bivariate analyses indicated that participants who were 65 years and older needed more denture adjustments than patients younger than 65 years (p = 0.0343). Participants who had worn overdentures for more than 5 years were more likely to require denture remakes (p = 0.0304). Participants who wore their dentures only during the day were less likely to require repairs (p = 0.0403). Participants who did not take any medications were significantly less likely to require denture base repairs (p = 0.0258). For the 35 participants who returned for recalls at all 4 time points, males were more likely to need denture teeth repaired or replaced (p = 0.0335) and those aged 50 to 64 were more likely to need 2 or more adjustments (p = 0.0311). No overdenture abutments were lost by the participants in this study. According to the results of this study, age, medication usage, denture-wearing habits, and age of the overdentures were significant factors associated with denture maintenance needs. Persons wearing overdentures need regular recalls, because they have continuing maintenance needs.

Bar-retained Tooth-supported Maxillary Overdenture—A Case Report

The maintenance of the bone anatomy requires a certain amount of daily stress/strain stimulus. Loss of teeth leads to alveolar ridge resorption, inefficient mastication, altered speech, and lowered confidence. A traditionally complete denture was the treatment of choice. Preventive prosthodontics aims at avoiding complete edentulism. Overdenture treatment is emphasized by preventive prosthodontics, which uses abutment teeth for support and hence allows the retention of remaining natural teeth. Advances in technology have introduced attachment-retained overdenture, which act as stress redirector and shock absorber and also offers several advantages over complete denture like superior retention, support, stability, psychological benefits, and proprioception. This article presents a case report that describes the steps involved in a bar-retained tooth-supported maxillary overdenture with a 2-year follow-up.
