Abstract Surgical extrusion is a recognised treatment option for teeth that have insufficient coronal tooth structure remaining due to deep caries, resorption or traumatic injury. However, the technique has not been widely adopted, arguably because extraction of a severely compromised tooth may be difficult to achieve in a gentle and predictable way. In this paper, we present our novel approach to surgical extrusion and subsequent management of teeth using a vertical extraction system (Benex), which has become the method of choice in the authors' practice for many teeth that would otherwise be deemed unrestorable. We describe the clinical procedure in detail and discuss the advantages and disadvantages compared to alternative approaches, including surgical crown lengthening and orthodontic extrusion.

Post endodontic restoration in cases of grossly destructed teeth are difficult as the available tooth structure is less, margins are subgingival and of compromised prognosis because the restoration might encroach upon the periodontium affecting its status to deteriorate. Interdisciplinary approach using forced eruption or Orthodontic extrusion along with minimal surgical crown lengthening can give adequate supragingival tooth surface for proper restoration and protect its root support from getting violated. This is the case report of an unsalvageable tooth that is restored to satisfactory functional and esthetic restoration utilizing interdisciplinary approach.

Novel Approach

Progress toward the development of brain-computer interfaces has signaled the potential to restore, replace, or augment lost or impaired neurological function in a variety of disease states. Existing brain-computer interfaces rely on invasive surgical procedures or brain-penetrating electrodes, which limit addressable applications of the technology and the number of eligible patients. Here we describe a novel approach to constructing a neural interface, comprising conformable thin-film electrode arrays and a minimally invasive surgical delivery system that together facilitate communication with large portions of the cortical surface in bidirectional fashion (enabling both recording and stimulation). We demonstrate the safety and feasibility of rapidly delivering reversible implants containing over 2,000 microelectrodes to multiple functional regions in both hemispheres of the Gottingen minipig brain simultaneously, without requiring a craniotomy, at an effective insertion rate faster than 40 ms per channel, without damaging the cortical surface. We further demonstrate the performance of this system for high-density neural recording, focal cortical stimulation, and accurate neural decoding. Such a system promises to accelerate efforts to better decode and encode neural signals, and to expand the patient population that could benefit from neural interface technology.

Crown Lengthening

The surgical procedure for the clinical crown lengthening, aims for an aesthetic or functional form to compensate for the reabsorption of the alveolar bone tissue caused by the invasion of the biological space. The conditions that must be taken into account during surgical planning are related to an excessive gingival exposure, altered passive eruption and lack of height of the dental element for restorative purposes. The objective of this systematic review was to evaluate in the scientific literature the minimally invasive surgical techniques used to clinical crown lengthening. A systematic review of the literature was performed using the databases, Science Direct, Embase, Cochrane Collaboration Library, and PubMed/MEDLINE. The search strategy provided a total of 157 studies. After selection, five articles met all the inclusion criteria and were included in this systematic review. Studies have shown that conventional surgical techniques for clinical crown lengthening are presented as an effective approach that promotes good aesthetic and functional results. However, they have some limitations. After evaluating the minimally invasive surgical techniques included in this systematic review, it was possible to infer that they presented satisfactory results in the soft and hard tissue contouring, with no complications and dissatisfaction being observed by the patients.

This article will focus on the active management of localized anterior tooth wear using indirect resin composite restorations. Emphasis will be placed on minimally invasive methods of tooth preparation in order to preserve biological tooth tissue in an already compromised tooth structure. Active management commits the patient to considerable long-term maintenance and it is important, as with any treatment, that the advantages and disadvantages are fully explained to the patient. CPD/Clinical Relevance: Numerous epidemiological studies have reported tooth wear to be increasing in incidence amongst the general population. This article aims to provide a methodical conservative approach in the management of the worn dentition.

Introduction: Anterior tooth fracture is the most commonly presenting clinical condition during routine dental practise. Restoration of such tooth is challenging task due to fracture position and amount of remaining coronal tooth structure. Tooth fracture at or below the gingival level usually have a poor prognosis. Treatment options for such clinical conditions range from tooth extraction to prosthodontic rehabilitation with surgical crown lengthening and/or orthodontic extrusion. This clinical report describes a multidisciplinary approach for management of such cases by the orthodontic forced eruption and clinical crown lengthening followed by the final restoration with indirect resin customized post core and crown.

AbstractLoss of tooth structure in the esthetic region is a big challenge for restorative dentist as it not only involves the establishment of tooth structure but also complies microesthetics. If the tooth structure is lost near the gingival margin, then the periodontal aspect cannot be overlooked. Surgical crown lengthening and orthodontic extrusion of the remaining tooth structure are two possible treatment modalities for such cases. Which one is best suited depends on the indications for each procedure. This study reports an orthodontic extrusion for the restoration of fractured upper canine. Preference of crown lengthening by orthodontic extrusion over surgical crown lengthening is clarified along the case discussion.
