Esthetic Management of Maxillary Anterior Teeth in a Patient with Midline Diastema Having Deep Bite Using Palatal Loop Connector: A Case Report

Esthetic rehabilitation utilizing concept of golden percentage and loop connectors: A clinical report

Rehabilitation of a missing tooth with a Fixed Dental Prosthesis is a commonly used treatment option with proven clinical results and longevity. Recreating good proximal contacts is the key to successful rehabilitation. However, in clinical situations where a certain amount of diastema may be desired by the patient or deemed necessary by the clinician to achieve esthetic treatment, use of loop connectors is necessary. Digital evaluation of the tooth material arch length discrepancy and following esthetic proportions like golden percentage ensures a well planned treatment procedure and a more predictable treatment outcome. This case report highlight rehabilitation of a missing anterior tooth in esthetic zone utilizing digital planning software and using loop connector to maintain esthetics. The intent of this case is to highlight loop connector as a viable treatment option for maintenance of diastema in cases where desired and the use of simple, commonly available software to implement esthetic proportions in designing of restorations.

Single Anterior Tooth Replacement By Maryland Bridge With Loop Connector: A Case Report

Restoring a single missing tooth in the mandibular anterior region is often a great concern to the dentist because it requires unnecessary removal of healthy abutment tooth structure. Also because of the drifting of the teeth may reduce the available pontic space or presence of diastema before can result in excessive mesiodistal space which again compromises the aesthetics. When the patients demand more conservative and less invasive treatment options, a combination of Maryland Bridge with a loop connector may be the best alternative option to restore the missing teeth whenever the diastema is present. It is the modification of resin bonded FPD which offers a simple solution when the above dilemma is present. It consists of a loop on the lingual aspect, joining the pontic in the center, and then attaches to the wing retainer on the abutment tooth. This case report provides a straightforward and innovative method for the fabrication of modified resin bonded FPD along with maintaining diastema.

A Wireless, Battery-Free Embedded Sensor for Monitoring Tension on a Suture Anchor

A passively powered wireless sensor based on an inductive-capacitive-resistive (LCR) sensor was developed to measure tensile stress at suture anchors used to repair soft tissue injuries such as ligament and tendon tears. The sensor, which is completely embedded within the suture anchor, consists of a strain gauge mounted on a substrate with a loop connector so a suture can pass through. When the suture experiences a tensile stress, it pulls at the loop connector and the strain gauge, allowing measurement of tensile stress at the suture. In this study, sensors of different designs were fabricated and characterized ex vivo to determine their force sensing capabilities. The effects of sensor placement and orientation on accuracy were also characterized. The LCR suture anchor sensor can be used to assess the quality of soft tissue treatments, such as rotator cuff repairs, as well as to detect failure of the implant post-surgery. The advantages of this sensor are its small size, wireless detection, and battery-free operation, making it ideal for use with both short- and long-term implants.

The modification of split pontic as non-rigid connector in the management of pier abutment

In long-span fixed partial denture restoration, especially when pier abutment is present, a non-rigid connector as a stress breaker is indicated. The Non-rigid connector is classified into a dovetail, loop connector, split pontic, cross-pin, and wing. Split pontic is an attachment placed entirely inside the pontic, particularly indicated in the tilted abutment case, to prevent the box preparation of distal pier abutment. This case report presents A pier abutment case treated with long span porcelain fused to the metal fixed movable bridge using dovetail shaped attachment, assembling the split pontic as a non-rigid connector. Split pontic acts as the stress breaker to prevent the pier abutment acts as a fulcrum. Split pontic also transfers the shear stress to the alveolar bone, minimalizes the mesiodistal torquing of the abutment teeth, and enables individual tooth movement. The advantages of this design are preparation with minimal reduction and better esthetic outcome as the porcelain build up can be done. Thus, there is no metal exposure of the restoration. Longevity and success of fixed partial denture restoration depend on the size, shape, type, and connector position. In pier abutment cases, a non-rigid connector must be considered one of the treatment choices to restore the missing teeth and preserve the abutments.KEYWORDS: pier abutment, split pontic, non-rigid connector

Maintenance of diastema with a loop connector fixed partial denture: A Case Report

The replacement of a single maxillary central incisor is a unique prosthodontic challenge from esthetic as well as a functional point of view. Loss of anterior teeth with existing natural diastema presents problems such as increased mesiodistal space available for pontic which makes it very difficult to give conventional fixed prosthesis with rigid connector and wider pontics can be very unesthetic to look in the esthetic zone. This clinical situation is a major challenge for a prosthodontist; leaves him in a dilemma whether to close the space or to maintain it in a final fixed prosthesis simulating the natural tooth appearance. If implant-supported prosthesis is not possible fixed partial denture along with loop connector is the best solution to maintain the existing diastema and esthetics. This article presents a case report where fixed partial denture along with loop connector was used to achieve esthetic rehabilitation in maxillary anterior region maintaining natural existing diastema.

Anterior esthetic rehabilitation using a casted palatal loop connector

This article aims to demonstrate an esthetic rehabilitation of the anterior teeth region with increased prosthetic space with a fixed prosthesis without compromising esthetic proportions. In cases where excess pontic space is present, the use of a conventional prosthesis would jeopardize the esthetic proportions to maintain the integrity of the prosthesis. A loop connector, which is usually a spring cantilever connector system, can be advocated in such cases to re-establish form without obliterating preexisting spaces or diastema. This case report demonstrates prosthetic rehabilitation of a missing anterior tooth in a 37-year-old female patient with an increased pontic space using a loop connector system that takes bilateral support to better support the prosthesis functionally from the abutments and the palatal tissues that it is rested upon in close adaptation with. In situations that pose constraints in placing an isolated implant-supported prosthesis, a loop connector fixed prosthesis is warranted, to maintain spaces around the pontic that would not compromise with the esthetics and even mechanically sustain well.

Loop Connectors to Restore Maxillary Anterior Teeth with Diastema-A Case Report

Restoring single missing anterior teeth is a challenging situation for the prosthodontist. In patients with increased interdental spacing or midline diastema, replaced with conventional fixed dental prosthesis affects the esthetics of the patients due to increase in size of the clinical crown. For such kind of clinical cases; loop connector will be a solution to enhance esthetics, maintain interdental spacing and proper emergence profile. This case report describes the successful management of diastema with fixed dental prosthesis with loop connector.

Loop Connector use for replacing a functional maxillary posterior tooth

Complex challenges in restorative dentistry are those that involve fulfilling both masticatory and esthetic function like restoring a premolar. While different modalities of prosthetic options like implants, conventional and resin-bonded fixed partial dentures, a clear vision of the completed restoration is mandatory before starting any construction work. Tooth migration into partial edentulous spaces reduces available pontic space, making it more difficult to restore aesthetics. We present a case of a young male patient who presented with such a clinical situation. A unique design of a loop connector was devised to fulfil the treatment objectives. The patient was happy and expressed his satisfaction with the design of the partial denture.

Twin cantilever twin loop connector fixed partial denture to restore diastema

Characterization in a removable partial denture is easily accomplished to achieve treatment objectives. In fixed partial denture characterization is mainly seen in the form of imparting different stains in the restoration. Characterization of designing fixed partial denture is necessary when diastema has to be incorporated within a fixed partial denture to overcome the problems associated with an increased mesiodistal width of partial edentulous spaces. We present a case of a young female patient who had a Kennedy class 3 partial edentulous situation with an anterior open bite and wide generalized diastemas. A specially designed two cantilever prosthesis was fabricated using a loop connecter between the pontic and the respective retainer. The reasons for choosing such a design was influenced by existing occlusion. Individual cantilever prosthesis connected by a loop connector provided a uniform and esthetic distribution of diastema within the fixed partial denture.

Diastema Beautified - A case report

Esthetic concerns about the smile often are the patient’s main reason for seeking dental care. The prosthetic rehabilitation of a single missing anterior tooth has always been a challenging task for a clinician. Achievement of these esthetic goals presents many challenges, including occasional differing opinions between patients and clinicians as to what constitutes an esthetic smile. Replacement of the single missing anterior tooth can be accomplished by a conventional fixed dental prosthesis as well as a dental implant supported restoration. Very often, drifting of teeth into the edentulous area causes a hindrance in the restoring process. This may reduce the available pontic space and in certain situations, where a diastema exists before an extraction may result in an excessive mesiodistal dimension to the pontic space. Hence, to address this problem loop connectors fixed dental prosthesis provides a simple solution to deal with excessive mesio-distal pontic space with the maintenance of the diastema. This case report presents a treatment option to achieve ideal esthetics by providing a loop connector to address the case with excessive space in the anterior region.

Using loop connectors as an interim mode of treatment: An interdisciplinary approach

To tackle a large midline diastema and generalized spacing existing before extraction often poses a challenge to the treating prosthodontist. The situation becomes even more complicated if the patient is a teenager, with multiple missing teeth, associated deep bite and where the jaw bone growth has not yet been completed. Possible treatment options would include a removable prosthesis, a fixed partial denture or an implant supported prosthesis. Treating such cases with a simple removable prosthesis cannot be justified if a deep bite existed which would result in posterior disocclusion. Also a conventional fixed partial denture or closure of the diastema with light cure composite (LCC), would result in a seemingly large tooth, which would be unaesthetic in appearance. Implant supported prosthesis is a possibility, if the patient's jaw bone growth has been completed. Another simple non-invasive solution to this problem would be to fabricate a non-rigid connector using loops. This presentation describes the procedure for fabrication of an interim loop connector for a 16 year old female patient who had lost one of her maxillary central incisors as a result of trauma. Patient also had multiple spacing in the maxillary anterior teeth and an associated deep bite. Her cephalogram revealed that she had a Class III skeletal pattern. A permanent treatment at this stage was not possible due to ontoward mandibular growth pattern as revealed on the cephalogram. Hence to dodge all these problems, a simple and non-invasive treatment using loop connectors was chosen till the growth period was completed.

Mandibular Loop Connector: An Underrated Treatment Modality

ABSTRACT Connectors are the components of fixed dental prosthesis that join the individual retainers and pontics together. Connectors may be rigid or nonrigid. Loop connector is a type of rigid connector, indicated primarily when an existing diastema is to be maintained in a planned fixed prosthesis. Such cases can be treated with an implant supported prosthesis or a fixed prosthesis using a loop connector. In case of loop connector, the connector is in the form of a loop on the lingual aspect of the prosthesis that connects the adjacent retainer and pontic. Similarly, loop connector can also be used in the mandibular anterior region for replacement of central incisors, using canines as abutments rather than mandibular laterals which usually have compromised bone support. There are many reports in literature describing the use of a loop connector in the maxillary anterior sextant. But, there are seldom reports about the use of a loop connector in the mandibular anterior region. This case report describes the use of a mandibular loop connector for the replacement of mandibular teeth where the adjacent teeth are periodontally compromised.

“Resin Bonded Loop Connector Fixed Partial Denture – A Subtle Solution to Maintain Midline Diastema”

Spacing between natural teeth is considered as a normal characteristic of class 1 malocclusion which is due to its high prevalence. However, spacing in the midline of the natural dentition has always been an area of interest for a prosthodontist. The challenge is so severe that most of the times its incorporation is part of treatment plan rather than any attempt to eliminate it, because midline diastema closure with a fixed prosthesis usually results in esthetic failures. With advances in dental cements especially resin cements; there has been an increase in delivery of resin bonded prosthesis, but has not been explored for possibility of maintaining midline diastema. This article presents a case of midline diastema successfully maintained by resin bonded prosthesis through the use of a loop connector between the pontic and the retainer.

Anterior Loop Connector Fixed Partial Denture - A Case Report

Replacement of anterior teeth with ridge defect and diastema is a complex challenging scenario with regards to prosthesis as well as esthetics. Different aesthetic treatment options such as implant supported restoration, conventional fixed partial denture and removable partial denture need be explored in treating such a patient. Problems posed may include drifting of teeth into edentulous areas which may reduce available pontic space, whereas diastema existing before an extraction may result in excessive mesiodistal dimension of pontic space. In such cases, loop connectors may be used to maintain the diastema in a planned fixed prosthesis. This article aims to describe the procedure for the fabrication of a loop connector fixed partial denture to restore an excessively wide anterior edentulous space in a patient with existing spacing between the maxillary anterior teeth.

ANTERIOR LOOP CONNECTOR FIXED PARTIAL DENTURE IN REPLACING MISSING CENTRAL INCISOR: A CASE REPORT

ABSTRACT Replacement of single anterior tooth is a complex, challenging procedure that can be accomplished with implant-supported restorations as well as conventional porcelain-fused-to-metal and resin-bonded fixed partial dentures. Different esthetic treatment options must be explored iri treating such patients. Drifting of teeth into the edentulous area may reduce the available pontic space; whereas a diastema existing before an extraction may result in excessive mesiodistal dimension to the pontic space. Although rarely used, loop connectorsare sometimes required to address this problem of excessive mesio-distalpontic space. Loop connectors offer a simple solution for a situation involving an anterior edentulous space albeit with the maintenance of the diastema. This article presents a case with excessive space in the anterior region treated witha loop connector to achieve ideal esthetic results in the maxillary anterior segment.

Anterior loop connector fixed partial denture: A simple solution to a complex prosthodontic dilemma

Drifting of teeth into the edentulous area may reduce the available pontic space; whereas a diastema existing before an extraction may result in excessive mesio-distal width to the pontic space. Although rarely used, loop connectors are sometimes required to address this problem of excessive mesio-distal width pontic space. The loop may be cast from sprue wax that is circular in cross section or shaped from platinum-gold-palladium (Pt-Au-Pd) alloy wire. Loop connectors offer a simple solution to the above mentioned dilemma, involving an anterior edentulous space albeit with the maintenance of the diastema. This article describes the procedure for the fabrication of a loop connector fixed partial denture to restore an excessively wide anterior edentulous space in a patient with existing spacing between all the maxillary anterior teeth.
