RESUMO

Crown lengthening is one of the most common surgical procedures in periodontal practice. Its indications include subgingival caries, crown or root fractures, altered passive eruption, cervical root resorption and short clinical abutment, and its aim is to re-establish the biologic width in a more apical position. While the procedure in posterior areas of the dentition has been thoroughly investigated, crown lengthening performed for esthetic reasons in the anterior areas is still a matter of debate and an evidence-based technique is not available. This paper provides accurate descriptions of the surgical and restorative phases of the esthetic crown-lengthening procedure by answering the following questions: what is the ideal surgical flap design? how much supporting bone should be removed? how should the position of the flap margin relate to the alveolar bone at surgical closure? and how should the healing phase be managed in relation to the timing and the position of the provisional restoration with respect to the gingival margin?

RESUMO

AIM: The aim of this study was to compare the clinical outcomes and soft tissue rebound following Fibre Retention Osseous Resective Surgery (FibReORS) and Osseous Resective Surgery (ORS) over a 48-month period. MATERIALS AND METHODS: Thirteen chronic periodontitis patients, displaying two contra-lateral posterior sextants with residual intrabony defects ≤3 mm in single-rooted or multi-rooted teeth with no or grade I furcation involvement, were treated in a split-mouth study model. ORS procedure was randomly applied on one side, while FibReORS on the contra-lateral side. Clinical measurements were recorded at 12 and 48 months after surgery. RESULTS: All 13 patients were available for the 48-month recall. At this time point, probing depth (PD) and keratinized tissue changes did not significantly differ between treatments. FibReORS-treated sites exhibited less gingival recession than ORS-treated sextants (2.1 ± 0.3 versus 2.5 ± 0.4 mm, p = .001), but comparable coronal soft tissue rebound. The mean difference of 0.4 ± 0.3 mm was consistent with higher amount of bone resection in the ORS group (0.92 ± 0.11 versus 0.38 ± 0.09 mm, p < .001). CONCLUSION: FibReORS resulted in similar PD changes and soft tissue rebound compared with ORS in posterior teeth with no or limited furcation involvement.

RESUMO

This study evaluated use of a solid-state laser to avoid the flap technique and suturing. An Er:YAG laser was used in 26 consecutive patients referred for osseous crown lengthening in 32 posterior teeth. The distance from the planned restoration margin to the alveolar crest (B) satisfied a 3-mm dentogingival complex. No tissue necrosis and no significant change in the distance from the gingival margin to B or probing depth were detected at 3 and 6 months. Minimally invasive Er:YAG laser surgery decreases the time needed to establish the gingival margin necessary for definitive restoration.

RESUMO

The purpose of this study was to evaluate the effects of segmental osteotomy on the blood vessels and osteoclasts in rats using micro-computed tomography (micro-CT) and histomorphometric analysis. After segmental osteotomy was performed around the maxillary first molars of 36 male Sprague-Dawley rats (n = 72), the samples were divided into a control group (no displacement), 0.5 D group (0.5 mm buccal displacement) and 1.0 D group (1.0 mm buccal displacement) (n = 24/group). At 1, 2, 4 and 8 weeks after surgery, changes in the blood vessel volume were investigated using micro-CT with perfusion of radiopaque silicone rubber. Tartrate-resistant acid phosphatase (TRAP) staining was used for histomorphometric analysis. Two-way repeated measures analysis of variance (rmANOVA) was performed to compare the volume of blood vessels and number of TRAP-positive osteoclasts among the groups. Regarding blood vessel volume, the displacement groups had no significant effects, while the time points had significant effects (p = 0.014). The blood vessel volume at 1 week was significantly smaller than that at 2, 4, and 8 weeks (p = 0.004, p = 0.026, and p = 0.005, respectively). Regarding TRAP cell count, the displacement groups had no significant effects, while the time points had significant effects (p < 0.001). The number of TRAP-positive osteoclasts at 8 weeks was significantly smaller than that at 1, 2, and 4 weeks (p < 0.001, p < 0.001, and p = 0.002, respectively), and the count at 4 weeks was smaller than that at 1 week (p = 0.011). Therefore, a regional osteoclast-related acceleratory phenomenon was maintained until 4 weeks after surgery.

RESUMO

PURPOSE: The treatment of patients with medication-related osteonecrosis of the jaw (MRONJ) is challenging. The purpose of the present study was to estimate the frequency and identify the factors associated with clinical improvement during treatment. PATIENTS AND METHODS: We designed and implemented a retrospective cohort study and enrolled a sample of subjects diagnosed with MRONJ between 2004 and 2015. The primary predictor variables were a set of heterogeneous variables grouped into the following categories: demographic (age and gender) and clinical (location of necrosis, therapy duration, medication type, disease stage, and treatment type). The primary outcome variable was the treatment outcome, defined as stable or worse and improved or healed. The descriptive, bivariate, and multiple logistic statistics were computed, and statistical significance was defined as P < .05. RESULTS: The sample included 337 subjects with a mean age of 68.9 years. Of the 337 subjects, 256 were women (76%). A total of 143 patients (42.2%) experienced spontaneous necrosis. Twenty-four (7.1%) had had exposure to targeted antiangiogenic agents. Those with stage 1 or 2 disease were more likely to have better outcomes than those with stage 3 disease (stage 1, adjusted odds ratio [OR] 3.4, P = .005; stage 2, adjusted OR 2.2, P = .03). Treatment type was a significant variable. Subjects undergoing surgery were 28 times more likely to have a positive outcome than those receiving nonoperative therapy (adjusted OR 28.7, P < .0001). CONCLUSIONS: Subjects with MRONJ who presented with less severe disease or who underwent operative treatment were most likely to have improvement or complete healing of their MRONJ-related lesions.

RESUMO

OBJECTIVE: The aim of this study was to present the authors' experience with a new surgical technique to correct mild laterognathia and malocclusion by means of an L-inverted midline osteotomy. PATIENT AND METHODS: The patient was a 26-year-old woman diagnosed with left laterognathia and ipsilateral posterior crossbite. She was operated by using this novel technique in November 2009 at Hogar Clínica San Rafael, Maracaibo, Venezuela. Bicortical midline symphyseal vertical osteotomy was executed, followed by block removal of the central right inferior incisor and its surrounding alveolar bone. The mandibular segmentation was completed by means of a right hemimentoplasty. After this, a 4-mm right mandibular rotation was made, and titanium plates and monocortical screws of the 2.0 system were used to achieve the rigid fixation. RESULTS: The patient showed outstanding aesthetic and functional results after 5 years. CONCLUSIONS: This technique provides a new treatment option for the correction of mild laterognathia cases associated with dental malocclusion.

RESUMO

Crown lengthening surgery aims to increase the amount of supragingival tooth tissue by resection of the soft and/or hard tissues to enable otherwise unrestorable teeth to be restored by increasing the retention and resistance forms of the teeth. Restoration of the worn dentition may require significant prosthodontic knowledge and skill. A prosthodontist should be involved from the beginning of the management of the patient. A number of key stages should be considered for correct management. Although the periodontist may guide the prosthodontist with regards to what may or may not be possible surgically, the overall treatment plan should be prosthodontically driven. Clinical Relevance: Toothwear of the anterior dentition provides a unique challenge to restore not only function but also to manage the aesthetic demands of the patient. To ensure that the correct outcome is reached, clinicians should be familiar with the normal anatomical proportions and relationships to enable planning and treatment to take place.

RESUMO

This is the first article in a two-part series which aims to provide an overview of the different techniques used to increase clinical crown height. In the first paper, the focus will be on the management of patients who present with gingival tissue excess. The different aetiologies are discussed and illustrated with clinical cases, following which a range of procedures that may be employed in the management of these patients are presented. With an increasingly ageing population, more patients are taking regular medications prescribed from their general medical practitioner, and so having a working knowledge of the specific drugs that may cause gingival enlargement is essential. Clinical Relevance: When patients with gingival tissue excess present in primary or secondary care, a clinician must have a good knowledge of the possible causes of the condition, as well as an idea of how the patient may be managed.

RESUMO

This is the second paper in this two-part series. Paper one provided an overview of managing gingival tissue excess and paper two will focus on increasing clinical crown height to facilitate restorative treatment. Crown lengthening is a surgical procedure aimed at the removal of gingival tissue with or without adjunctive bone removal. The different types of procedure undertaken will be discussed over the two papers. In order to provide predictable restorations, care must be taken to ensure the integrity of the margins. If this is not taken into account it can lead to an impingement on the biologic width, which may in turn lead to chronic inflammation resulting in recession or the development of periodontal problems which can be hard to manage. Clinical Relevance: This paper aims to reinforce the need for thorough diagnosis and treatment planning and provides an overview of the various procedures that can be undertaken.

RESUMO

PURPOSE: Although treatment of cleft lip and cleft palate is becoming standardized, treatment of alveolar cleft remains controversial. Thus, preclinical animal work remains necessary to improve clinical outcome. This study established an alveolar cleft model in the rat. MATERIALS AND METHODS: Maxillary first molars were extracted to create a 4- × 4- × 3-mm complete alveolar cleft on the right and left sides in 25 8-week-old Sprague-Dawley rats. The left cleft was filled with bone wax and the right side remained untreated. Animals were sacrificed at 0, 4 and 8 weeks after surgery. Harvested alveolar cleft samples were evaluated by micro-computed tomographic and histologic analyses. RESULTS: The healing rate and osteoblast activity of the left cleft were less than those of the right cleft. CONCLUSION: This model of a critical-size alveolar cleft can be used efficiently for the therapeutic evaluation of novel techniques for the treatment of alveolar cleft.

RESUMO

BACKGROUND: The aim of this study was to assess soft-tissue re-growth following Fibre Retention Osseous Resective Surgery (FibReORS) or Osseous Resective Surgery (ORS) over a 12-month healing period. MATERIAL AND METHODS: Thirty patients with chronic periodontitis showing persistent periodontal pockets at posterior natural teeth after cause-related therapy were enroled. Periodontal pockets were associated with infrabony defect ≤3 mm; 15 patients were randomly assigned to FibReORS (test group) and 15 to ORS (control group). Measurements were performed by a blind and calibrated examiner. Soft-tissue rebound after flap suture was monitored by changes in gingival recession at 1-, 3-, 6-, and 12- month follow-up. Multilevel analysis considering patient, site, and time levels was performed. RESULTS: Greater osseous resection during surgery and higher post surgical gingival recession was observed in the ORS group. The mean amount of soft-tissue rebound following surgery was 2.5 mm for ORS-treated sites and 2.2 mm for FibReORS-treated sites. Approximately 90% of the coronal re-growth was detectable after 6 months for both procedures. The interaction between ORS and time of observation showed a higher soft-tissue rebound after 12 months (p = 0.0233) for ORS-treated sites. CONCLUSIONS: Both procedures showed a similar coronal soft-tissue re-growth with a significant higher recession reduction for ORS-treated sites. Significant clinical stability of the gingival margin is obtained 6 months after surgery for both procedures.

RESUMO

AIM: The aim of this split-mouth clinical trial was to compare the effectiveness of Apically Positioned Flap with Fibre Retention Osseous Resective Surgery (FibReORS) or Osseous Resective Surgery (ORS) in the treatment of periodontal pockets associated with intrabony defects ≤ 3 mm at posterior natural teeth. MATERIALS AND METHODS: Twenty-six posterior sextants requiring osseous resective surgery were selected in 13 chronic periodontitis patients: 13 sextants were randomly assigned to ORS and 13 to FibReORS. Clinical evaluation of probing depth (PD), gingival recession and clinical attachment level was performed at baseline, 6 and 12 months postoperatively. Periapical radiographs were taken prior and after surgical treatment, at 6- and 12-month follow-up. RESULTS: Ostectomy amounted to 1.0 ± 0.3 mm in the ORS group and to 0.4 ± 0.2 mm in the FibReORS group. At 12-month examination PD changes did not significantly differ between the experimental groups. ORS group showed significantly (p < 0.001) greater clinical attachment loss (2.2 ± 1.0 mm versus 1.0 ± 0.6 mm), radiographic bone resorption (0.43 ± 0.08 mm versus 0.13 ± 0.09 mm) and post-operative patient discomfort compared to FibReORS. CONCLUSION: FibReORS resulted in similar PD reduction, but less ostectomy, clinical attachment loss and patient morbidity compared to ORS.

RESUMO

OBJECTIVE: The aim of the present study was to evaluate the effect of periodontal dressing on post-operative pain and swelling after surgical crown lengthening. MATERIALS AND METHODS: A blind, randomized, clinical trial was carried out with 36 patients. Following surgical crown lengthening, the individuals were randomly allocated to the periodontal dressing group (PDG) and control group (CG, non-placement of periodontal dressing). Pain and discomfort were analyzed using a visual analog scale (VAS), verbal scale (VS) and the number of analgesics consumed in 7 days post-operatively. Post-operative infection, stability of the gingival margin and type of healing were also evaluated. RESULTS: The PDG had a significantly higher percentage of responses of 'strong pain' on the VS in the first day post-operatively (33.3% vs 5.3%, p = 0.03) and greater pain on the first and second days post-operatively based on the VAS. Moreover, a significant difference between groups was found regarding gingival swelling after 7 days. However, gingival recession was found in 57.8% of the sites in the CG and only 5.5% of sites in the PDG. No change in condition was found among individuals with conjunctive tissue/bone exposure in the CG in the immediate post-operative period and 80% of the patients in the PDG had healing by first intention after 7 days. CONCLUSION: The use of periodontal dressing seems to be preferable following surgical crown lengthening with connective tissue/bone exposure. However, adequate post-operative analgesic strategies should be employed due to the possibility of intense pain in the first 24 hours.

RESUMO

The success of autogenous tooth transplantation depends on the vitality of the periodontal ligament attached to the donor tooth, and its viability decreases when it is exposed extraorally. This report describes the case of a 16-year-old patient in whom a rapid prototyped tooth model was performed using cone-beam technology and a surgical template guide for autotransplantation as an effective technique for a critical time-based procedure.

RESUMO

The correction of diastemas in the anterior region with composite resin is considered to be practical and conservative. Harmony between the restorative material and the periodontium is necessary to achieve satisfactory functional and esthetic results. Whenever excessive gingiva occurs in the interproximal region, removal is necessary to avoid excessively contoured restorations. A predictable technique is described to conservatively remove interproximal tissue in situations in which crown lengthening is required to treat bilateral diastemas. A surgical template based on the diagnostically waxed cast was produced to serve as a reference during periodontal surgery.
