Crown lengthening is a surgical procedure designed to increase the extent of the supragingival tooth structure, so that the clinician can restore the tooth. Crown lengthening procedure is done to maintain normal biologic width and increase crown length for retention of prosthesis. Various techniques have been proposed to perform CLP, such as gingivectomy, undisplaced flap with or without osseous reduction, apically repositioned flap with or without bone reduction, and orthodontic forced eruption with or without fibrotomy. Selection of one of this CLP technique depends upon esthetics, clinical ratio of crown to root, structure of root, location of furcation, position of tooth and the capacity of the tooth to be restored. This case report illustrate two different methods of doing crown lengthening procedure the selection of case depends upon various soft tissue and hard tissue parameters. Owing to the various advantages, disadvantages and associated limitation with different methods, we opted for surgical CLP with scalpel method. Uneventful healing was observed in both our cases. No post-operative complications was observed in both cases. Thus to conclude success rate of CLP is high but appropriate selection of case is required. In our case report both the methods of CLP shows significant result in increasing the crown length and maintaining the biological width.

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.

Crown Lengthening

The relationship between the periodontal health and the restoration of teeth is intimate and inseparable. Maintenance of gingival health constitutes one of the keys for tooth and dental restoration longevity. An adequate understanding of relationship between the periodontal tissue and restorative dentistry is essential to ensure adequate form and function of dentition and Esthetics and comfort to the patients. Restoration of fractured (traumatized), severely decayed, partially erupted (delayed passive eruption), worn or poorly restorated teeth is often difficult for the dentist without surgical and orthodontic intervention. Surgical crown lengthening of these teeth is necessary to provide adequate tooth structure for restoration or Esthetics enhancement, thus adhering to basic biological principles by preventing impingement on the periodontal attachment apparatus or biological width. Many clinicians have been unable to utilize the concept of biologic width in practical manner. Hence the purpose of this article is to describe the biologic width anatomy, evaluations and correction of its violation by different methods.

Surgical crown lengthening has been proposed as a means of facilitating restorative procedures and preventing injuries in teeth with structurally inadequate clinical crown or exposing tooth structure in the presence of deep, subgingival pathologies which may hamper the access for proper restorative measures. Histological studies utilizing animal models have shown that postoperative crestal resorption allowed reestablishment of the biologic width. However, very little has been done in humans.Aims. The purpose of the study was to evaluate the potential changes in the periodontal tissues, particularly the biologic width, following surgical crown lengthening by two surgical procedures before and after crown placement.Methods and Material. Twenty (20) patients who needed surgical crown lengthening to gain retention necessary for prosthetic treatment and/or to access caries, tooth fracture, or previous prosthetic margins entered the study. The following parameters were obtained from line angles of treated teeth (teeth requiring surgical crown lengthening) and adjacent sites: Plaque and Gingival Indices (PI) & (GI), Position of Gingival Margin from reference Stent (PGMRS), Probing depth (PD), and Biologic Width (BW).Statistical Analysis Used. Student “t” Test.Results. Initial baseline values of biologic width were 2.55 mm (Gingivectomy procedure B1 Group) and 1.95 mm (Ostectomy procedure B2 Group) and after surgical procedure the values were 1.15 mm and 1.25 mm.Conclusions. Within the limitations of the study the biologic width, at treated sites, was re-established to its original vertical dimension by 3 months. Ostectomy with apically positioned flap can be considered as a more effective procedure than Gingivectomy for Surgical Crown Lengthening.

Crown Lengthening

Short clinical crowns often lead to poor retention form, leading to improper tooth preparation. Crown lengthening is carried out to increase the clinical crown length without violating the biologic width. Several techniques have been proposed for crown lengthening such as gingivectomy procedures. A Cross-sectional, descriptive study was conducted in a university, on randomly selected individuals. The study group consisted of patients getting treated at the Department of Prosthodontics from June 2019 – March 2020. 86,000 case sheets were reviewed, and samples were selected using simple random sampling. The two variables were compared using the chi-square test. Laser gingivectomy was the most common 55.9% form of crown lengthening procedure. Awareness of crown lengthening was found more among postgraduates at 78.7%. Among all the departments, crown lengthening was required more for periodontal procedures 42.3%. In this era of quickly developing technologies and innovative ideas, the requirement for faster treatment has not only become a requirement but a necessity. Treatment with lasers is well accepted by patients as it is less time-consuming and painless. Lasers have taken over a lot of procedures so is crown lengthening. Postgraduates know more about crown lengthening and hence do in more number of cases. There are various reasons to get crown lengthening done with periodontitis being the most common specialty for its need.

Crown Lengthening

Complete crown fracture is a dental injury affecting enamel, dentin, and pulp and unfortunately crown is lost usually due to loss of tooth structure. Root-crown lengthening can be performed if an acceptable root-crown ratio is preserved for the retention of root. This paper presents a case report of a mandibular canine incisor tooth having complete crown fracture. Root-crown lengthening is performed by surgical extrusion of the root coronally, splintted using a semi-rigid splint and prognosis was successful after one year later. Treatment of complete crown fracture by surgical extrusion and splintting may be a good alternative for general practitioners since it is an easy and short time requiring technique necessiating less equipments.  How to cite this article: Yiğit Özer S, Uysal İ, Bahşi E.

Crown Lengthening

The aim of this case report was to describe the surgical sequence of crown lengthening to apically reposition the dentogingival complex, in addition to an esthetic restorative procedure. Many different causes can be responsible for short clinical crown. In these cases, the correct execution of a restorative or prosthetic rehabilitation requires an increasing of the crown length. According to the 2003 American Academy of Periodontology (Practice Profile Survey), crown lengthening is the most habitual surgical periodontal treatment.

The general dental practitioner must consider orthodontic extrusion of a tooth when a subgingival defect, such as, crown fracture occurs before prosthetic rehabilitation, especially in the aesthetic zone. Extrusion enables the root portion to be elevated which exposes sound tooth structure for placement of restorative margins. This case report describes the multidisciplinary management of a fractured upper first premolar in a general dental practice. The forced orthodontic eruption is achieved by an endodontic attachment and sectional fixed appliance with an offset placed in the wire. The ability to extrude premolars with this method is complicated by heavy occlusal forces, occlusal interferences, and short clinical crown length. The tooth was restored with a titanium post, composite core, and porcelain fused to metal crown. The entire course of treatment was carried out under National Health Scheme, UK and as a part of vocational training. The 21 months followup showed no change in occlusal contacts or gingival level.

Crown Lengthening

Osseous crown-lengthening is often needed to enhance the appearance of a patient’s smile, prevent the violation of biologic width, and/or provide sufficient tooth structure for the placement of final restorations. The present technique for osseous crown lengthening typically involves flap surgery, a procedure that frequently is associated with postoperative complications that can interfere with the aesthetic outcome, such as infection, bleeding, and change in tissue position during the healing process. The erbium laser enables the clinician to offer the patient a minimally invasive alternative to osseous crown lengthening negating the adverse effects associated with conventional treatment. Other advantages of using the laser for osseous crown lengthening includes: hemostasis, improved visualization, fewer postoperative complications and recession.

A tooth can be broken due to many reasons, out of which deep cervical caries can be the one leading to destruction of the whole buccal surface of the tooth. So, to preserve such kind of tooth, root canal treatment is the ultimate treatment option followed by proper selection of the restorative means of such endodontically treated tooth. endodontically treated tooth (ETT) has loss of tooth structure and changes in physical characteristics. Therefore, proper selection of restoration for ETT is mandatory to maintain almost the same level of strength and regaining its functional abilities. The decision of doing restoration of endodontically treated teeth depends on many factors like the amount of tooth structure remaining, condition of the opposing tooth, etc. In cases of less than 50 % tooth structure remaining post and core followed by crown is the best treatment option. This article showcases a case report of treatment of anterior teeth with deep cervical caries. The posts used in these cases were fiber post which were luted and the core build up was done with ParaCore, which is a glassreinforced composite by Coltene. Deep cervical caries can lead to destruction of the whole buccal surface of the tooth. So, to preserve such kind of tooth, root canal treatment followed by proper selection of restoration for endodontically treated tooth is mandatory to maintain almost the same level of strength and to regain its functional abilities. This article showcases a case report of treatment of anterior teeth with deep cervical caries.
