ABSTRACT
@#With the growing maturity of implant technology, implant overdenture has gradually become a conventional repair method for edentulous patients to restore beauty and function, which improves the quality of life of edentulous patients. This paper reviews the effects of implant factors, attachment factors, occlusal factors and patients' own factors on residual alveolar ridge. Existing studies suggest that when designing denture, doctors first need to consider the oral mucosa and jaw conditions of patients before operation, and select the appropriate size of implant to ensure that sufficient bone remains around the implant; Secondly, when choosing the type of attachment, the number, location and A-P distance of implants should be fully considered, and the inclination of cusp should be properly reduced to avoid the harm of excessive lateral force to alveolar ridge; Finally, regular reexamination should be carried out after operation to maintain longer service time of denture and more sufficient bone mass of edentulous patients. However, there are many factors affecting jaw absorption. In the future, we should further explore many factors, such as patients' habit and frequency of wearing dentures, oral health and nutritional status, systemic diseases and medication.
ABSTRACT
The aim of this study is to evaluate bone loss around implants after delivery of implant supported over dentures using CBCT.This study was performed to evaluate Postoperative bone level around mandibular dental implants using cone beamcomputed tomography (CBCT). The study was conducted on 10 completely edentulous patients that were rehabilitated bycomplete overdentures Patients retained mandibular overdentures by two implants installed in the canine region andretained locator attachments. Standard clinical and laboratory techniques were followed for implant insertion and dentureconstruction for all patients. The implants were divided in two groups. Implants bearing locator attachment with blue nyloninsert (Group I) and implants bearing locator attachment with transparent nylon insert (Group II). The twenty insertedimplants were left undisturbed for three months to achieve osseointegration. The mesial, distal, buccal and lingual bonelevel around the dental implants was evaluated, using the CBCT i-CAT scan with Blue sky Plan® software. Bone level wasobtained at six and twelve months after loading. The CBCT measurements of bone level revealed that there was bone lossaround all aspects of the inserted twenty dental implants
ABSTRACT
The aging society of the global population has led to an increase in the number of patients with edentulous jaw, a common multiple disease. Given the developments in implant techniques, the method of implant denture has received a positive and good response in terms of the quality of life and psychological well-being of patients. Implant-supported overdenture in mandible has two main advantages. 1) It has better retention and chewing efficiency than those of mandibular conventional denture. The required implant site of implant-supported overdenture is less than that of fixed implant-supported denture and can repair more defect tissues to help restore beauty and pronunciation. The price of the former is more acceptable than that of the latter. Therefore, this article aimed to systemically analyze and further discuss the clinical effect of implant-supported overdenture in elderly patients; combine existing related studies on the selection of number, site, and upper restoration of implants; and illustrate the advantages of removable implant-supported protheses in the repair of toothless mandible.

The object of this case report is to introduce milled zirconia bar and PEKK female part made by CAD/CAM technology for bar attachment implant supported overdenture in maxillary edentulous patients. For over 2 years, in terms of function and esthetics, satisfactory result was obtained. Esthetically and functionally satisfactory results were obtained in periodic follow up check.

Objective:To evaluate the clinical effects of ball attachment and Locator attachment for implant-supported overdenture.Methods:67 cases with edentulous jaw were treated with 150 Straumann and Bego implants and implant-supported overdentures using ball attachments Locator attachments,respectively.All cases were followed up regularly,biological and mechanical complications were observed,the patient satisfaction after restoration was compared between groups.Statistical analysis was performed using SPSS 17.0 software.Results:Follow-up was completed in 58 cases,25 with ball attachment,26 with Locator attachment and 7 with ball changed by Locator.Biological complications comparison showed that the incidence of gingival hyperplasia in the ball group was higher than that in the Locator group(P ＜ 0.05).There was no statistical difference of mechanical complications between the 2 groups (P ＞ 0.05),but the incidence of all kinds of mechanical complications in the Locator group was less than those in the ball group,the average repair frequency of the ball and Locator group was 1.9 times and 0.9 times respectively.Patients'satisfaction on chewing and retention was higher in the Locator attachment group than that in the ball attachment group(P ＜ 0.05).No statistical difference was found in patients' satisfaction between genders (P＞0.05),and no correlation of satisfaction was found with patients' age and follow-up time.Conclusion:The clinical effects of implant-supported overdenture using the Locator attachment is superior to that using the ball attachment.
ABSTRACT
Diferentes desenhos de próteses totais implantossuportadas ou implantorretidas estão disponíveis para a reabilitação da maxila desdentada. Embora a preferência do paciente normalmente seja por uma reabilitação fixa, existem indicações claras onde a prótese removível é a mais recomendada. Muitos são os aspectos a serem considerados durante o planejamento buscando a decisão entre a prótese fixa ou removível. Portanto, o objetivo deste artigo foi apresentar e discutir os fatores clínicos presentes do desdentado superior que determinam a escolha do tipo de prótese, além de relatar um caso clínico de restauração de maxila desdentada. Um paciente usuário de prótese parcial removível superior apresentou-se com indicação de extração dos dentes remanescentes. Implantes imediatos e prótese total fixa provisória implantossuportada com carga imediata foram instalados. Após estabilização dos tecidos duro e mole, foram considerados aspectos como suporte labial, capacidade de higienização do paciente, entre outros, para eleição do tipo de prótese definitiva. Optou-se, então, pelo desenho final de uma prótese total implantossuportada removível, utilizando barra fresada parafusada com sistema de encaixes MK1.
Different designs of implant-supported or implant-retained prostheses are available for the rehabilitation of the edentulous maxilla. Although the patient's preference is usually for a fixed rehabilitation, there are clear indications where the removable prosthesis is the best option. There are many aspects on treatment planning to choose between a fixed or removable prosthesis. Therefore, the aim of this study is to present and discuss clinical factors that determine the choice of prosthesis, as well as to report a clinical case restoring an edentulous maxilla. A patient wearing an upper removable partial denture presented with hopeless teeth. Immediate implants were placed and restored with a full-arch provisional fixed implant-supported prosthesis. After stabilization of hard and soft tissues, factors such as lip support, oral hygiene levels, and other features were considered for the final restoration. Then, the final design included a removable implant-supported prosthesis over a milled bar and MK1 attachments.

A 23-year-old female with aggressive periodontitis was treated using dental implants and LAVA system. The severely compromised teeth were extracted irrespective of initial conservative periodontal treatment. An implant-supported overdenture with 4 implants was fabricated for the maxilla and all-ceramic restorations for the mandible. Esthetic and functional goals were achieved with team approach involving periodontists and prosthodontists. This case report describes a treatment procedure for a generalized aggressive periodontitis patient with severe bone resorption.
