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.

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.

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.

SUMMARY This article describes the case of a vital molar tooth with a vast furcal iatrogenic root perforation and biologic width violation, which was successfully managed by a multidisciplinary approach aimed at preserving pulp vitality. The root perforation was cleaned and then sealed with mineral trioxide aggregate, which was positioned onto the pulp at the canal orifices. After one month, the patient was not reporting symptoms, and the tooth was positively responding to the thermal test. The tooth was orthodontically extruded, subjected to minimally invasive crown lengthening, and prepared to receive a full-crown restoration. Radiotransparent composite resin was chosen as a permanent restorative material to better monitor possible endodontic complications at the coronal level. The patient's tooth was followed up for eight years uneventfully. The present case is an example of the possibility to subject a root-repaired tooth with fully formed apices to conservative yet complex multidisciplinary treatment while maintaining pulp vitality.

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.

The interaction between periodontology and restorative dentistry play an important role in many aspects including location of restorative margins, crown contours and response of all gingival tissues to restorative preparations. Most of the clinicians are aware of this interrelationship but the dilemma remains concerning specific concepts such as biologic width, its maintenance and applications of crown lengthening in cases of biologic width violation.

Crown Lengthening

Once the biologic width of the supporting periodontal attachment apparatus has been severely violated, more extensive procedures are often necessary to manage compromised root structure and supporting bone. Surgical techniques advocated are primarily corrective in nature and consist of root movement and repositioning or root removal and alteration of tooth morphology, with concomitant correction of the periodontium. Some indications for surgical corrective intervention to manage radicular perforations include extensive cervical resorption or traumatic perforation which extends well below the osseous crest in both single and multirooted teeth and damage to the furcation region of multirooted teeth which is not responding to nonsurgical therapy, is not amenable to simple surgical correction, or is complicated and compromised further by extensive periodontal disease. Common indications for orthodontic root extrusion include fractured tooth margins below crestal bone, deep carious margins, some isolated infrabony defects, and perforations from resorptions, post space preparation and aberrant access openings. When root extrusion is indicated to elevate a perforative root defect above the osseous crest; seldom is the desired result achieved without surgical crown lengthening. This is necessary to compensate for the coronal movement of the gingival attachment and alveolar bone which occurs with the tooth during eruption resulting in unacceptable esthetics. Although it is possible to extrude nearly any tooth the simplest cases are those that have single roots and an immediate proximal tooth on either side for appliance anchorage. Molars are generally difficult to treat as are the terminal teeth in the arch or free standing teeth.

ABSTRACT The best way to enhance gingival health and minimize trauma is to avoid contact of the gingivae with restorative materials. Subgingival finish lines are not periodontally advantageous. Crown lengthening is a periodontal resective procedure, aimed at removing periodontal tissue support to increase the clinical crown height. Periodontal health is of paramount importance to understand the concept of biologic width, indications, techniques and other principles as well as some possible limitations. This article aims to discuss these concepts and its relationship to periodontal health and restorative dentistry. The importance of restorative margin location and contours related to periodontal health are also addressed in order that the restorative dentist can use crown lengthening as part of an overall treatment plan in a controlled and predictable manner, taking into account biological factors.
