  • Severe mandibular bone resorption may cause difficulties in using a complete denture. An implant overdenture is a feasible and economical treatment option as it can improve retention, stability, and support. A Locator attachment has used successfully. Recently, the next generation of the Locator attachment launched. The purpose of this article is to describe the fabrication of an implant overdenture with a Locator R-Tx attachment as well as its features.

  • The purpose of this case report is to introduce new attachment system(milled titanium bar with $Locator^{(R)}$ attachment) for implant supported overdenture in maxillary edentulous patients. A 56-years-old male patient visited the hospital due to the mobility of his maxillary fixed partial dentures(10-unit bridge). Including temporomandibular joint(TMJ), there was no specific PMHs to influence dental treatment. In radiographic and clinical evaluation, there was a severe bone resorption and mobility in maxillary teeth. Accordingly all the remaining maxillary teeth was extracted and fabrication of implant supported overdenture was planned. The milled titanium bar with $Locator^{(R)}$ was designed as an attachment system, considering the stability and retention of denture, masticatory efficiency, oral hygiene care, esthetics, pronunciation, and patient's financial state. The milled titanium bar was manufactured using CAD/CAM technology, and $Locator^{(R)}$ attachment connected to the bar by tap & drill method. For over 1-year, in terms of function and esthetics, satisfactory result was obtained.

  • Loss of tooth results in remodeling and resorption of surrounding alveolar bone which causes atrophic edentulous ridge and gradually decreasing gingival attachment. As a result, edentulous patients face difficulty in using dentures due to pain, decrease of support, decline of masticatory efficiency of complete denture. To improve this, overdenture with implant in the mandible and attachment are considered as a treatment of choice as a favorable treatment. In this case, a patient with edentulous ridge for long period is rehabilitated by complete denture in maxilla and implant overdenture using Locator$^{(R)}$ attachment in mandible.

  • Due to the limitations of conventional removable partial denture prostheses to treat a cleft lip & palate patient who shows scar tissue on upper lip, excessive absorption of the maxillary residual alveolar ridge, and class III malocclusion with narrow palate and undergrowth of the maxilla, 4 implants were placed on the maxillary edentulous region and a maxillary removable implant-supported partial denture was planned using a CAD/CAM milled titanium bar. Unlike metal or gold casting technique which has shrinkage after the molding, CAD/CAM milled titanium bar is highly-precise, economical and lightweight. In practice, however, it is very hard to obtain accurate friction-fit from the milled bar and reduction in retention can occur due to repetitive insertion and removal of the denture. Various auxiliary retention systems (e.g. $ERA^{(R)}$, $CEKA^{(R)}$, magnetics, $Locator^{(R)}$ attachment), in order to deal with these problems, can be used to obtain additional retention, cost-effectiveness and ease of replacement. Out of diverse auxiliary attachments, $Locator^{(R)}$ has characteristics that are dual retentive, minimal in vertical height and convenient of attachment replacement. Drill and tapping method is simple and the replacement of the metal female part of $Locator^{(R)}$ attachment is convenient. In this case, the $Locator^{(R)}$ attachment is connected to the milled titanium bar fabricated by CAD/CAM, using the drill and tapping technique. Afterward, screw holes were formed and 3 $Locator^{(R)}$ attachments were secured with 20 Ncm holding force for additional retention. Following this procedure, satisfactory results were obtained in terms of aesthetic facial form, masticatory function and denture retention, and I hereby report this case.

Removable partial denture restoration using single implant supported with $Locator^{(R)}$ attachment in a crossed occlusion patient: a case report (다수치아를 상실한 엇갈린 교합 환자에서 임플란트와 $Locator^{(R)}$ attachment를 이용한 가철성 국소의치 증례)

  • When losing many of the remaining teeth, the relation among them can be put into dynamically unfavorable situation. In the case that the patient without any incompatibilityto the denture, overdenture can be considered. Moreover, we can overcome the dynamical disadvantage, and improve the support, stability, and retention of the partial denture by using implant at the edentulous area. In this case, patient with crossed occlusion between few remaining teeth was treated with maxillary and mandibular partial denture. Single implant fixture was placed at the edentulous space, opposing to the maxillary teeth occluded, and $Locator^{(R)}$ attachment was connected. The patient's esthetic satisfaction was improved by ideally adjusting the tilted occlusal plane. Since the patient was satisfied both esthetically and functionally, and maintained stable during the clinical observation for 6 months after the treatment, we would like to report about it.

  • It is difficult to provide prosthodontic treatment to fully edentulous patients with severe alveolar bone resorption, because this makes patents hard to endure functional load, and to adapt to the dentures, which result in emotional stress to patients. Implant supported overdenture can be chosen to solve these problems. Among several types of them, the implant retained and tissue supported overdenture, is available to the patients of low masticatory force with the reduced cost. Attachments also can be used for increasing retention and esthetics in dentures. Especially, $Locator^{(R)}$ system needs a small vertical interarch space for restoration and is able to compensate the difference of angle between fixtures. In this study, we restored maxilla with conventional complete denture, and mandible with implant and tissue supported overdenture and $Locator^{(R)}$ system.

  • Overdenture using dental implants could improve the problems of conventional complete denture function which are pain during mastication, insufficient retention and stability. Locator attachment used widely for implant-retained overdenture has advantages that it needs the smallest vertical space and also its nylon male cap allows personalized retention for each case. However its retention force decreases rapidly with function rather than the bar and ball attachment. So, implant fixture should be positioned as parallel as possible.

  • The retention of complete dentures in patients with Parkinson's disease is often poor due to their constant dislodgement by involuntary movements of the tongue and lips. Furthermore, insertion of the overdenture is expected to be difficult due to their limited voluntary movements. This case is about the bimaxillary overdenture restoration where its retention and stability are improved, using magnetic attachment of remained roots of maxilla and two implant $Locator^{(R)}$ attachments of mandible in patients with Parkinson's disease. This report describes the fabrication of this functionally improved prosthesis.

  • In crossed occlusion, displacement of removable partial denture is likely to occur during function due to different characteristics of abutment and supporting tissue. It increases discomfort to the patient. In addition, adverse effect on the residual ridge and abutment can induce an unfavorable prognosis of the denture. In this case, a small number of implants can be placed in strategic locations. Attachment can be added for additional support and retention of removable partial denture assisted by implants. This article describes the rehabilitation of a crossed occlusion patient using implant-assisted removable partial denture with Locator$^{(R)}$ attachment. After 24 months, the patient was satisfied with the aesthetic and function of the prosthesis that is maintained stable.
