Analysis of the treatment of RT2 recessions with a xenogeneic collagen matrix vs. connective tissue graft combined with a coronally advanced flap. A double-blinded randomized clinical trial.

Objectives: To compare the clinical efficacy in terms of mean root coverage in RT2 recession treated with a coronally advanced flap combined with a xenogeneic collagen matrix versus a connective tissue graft.

Materials And Methods: A total of 20 patients were randomized to receive one of two treatments: coronally advanced flap + xenogeneic collagen matrix (test group) and coronally advanced flap + connective tissue graft (control group). Patient-related outcomes measures and professional aesthetic assessment by root esthetic score were performed.

Clinical analysis of the tooth-implant papilla for two narrow-diameter titanium-zirconium implants in the anterior area: prospective controlled clinical study.

Background: Rehabilitation of the anterior area when the mesio-distal space is reduced is a challenge for the clinician, due to the patient's anatomical limitations and aesthetic requirements. Narrow Diameter Implants (NDI) are an option of treatment when the standard diameter implant is not possible, but the evidence is scarce. This prospective clinical study aims to analyze the formation of the tooth-implant papilla between the implant and the adjacent natural tooth in the maxillary lateral incisors and mandibular incisors.

Comparative study of the modified VISTA technique (m-VISTA) versus the coronally advanced flap (CAF) in the treatment of multiple Miller class III/RT2 recessions: a randomized clinical trial.

Objectives: To compare the percentage of mean root coverage (MRC%) obtained in the treatment of multiple Miller class III/RT2 gingival recessions using the modified VISTA (m-VISTA) technique versus the coronally advanced flap (CAF) technique, using a connective tissue graft (CTG) in both cases.

Materials And Methods: Twenty-four patients were randomly treated with m-VISTA (test group (TG) = 12) or CAF (control group (CG) = 12). A calibrated, experienced, and blinded examiner collected data related to multiple periodontal clinical variables, especially the recession (REC) in order to calculate the MRC% at 6 and 12 months, which was the primary outcome of the study.

Single tooth restoration in the maxillary esthetic zone using a one-piece ceramic implant with 1 year of follow-up: case series.

Background: Oral implants have helped clinicians to improve the quality of life for many patients. The material of choice for dental implants currently remains titanium type IV, whose mechanical and biological properties have been proven throughout the history of implantology. Yet, this material is not exempt from complications.

Complete root coverage in the treatment of Miller class III or RT2 gingival recessions: a systematic review and meta-analysis.

Background: The primary objective of this systematic review and meta-analysis was to assess the evidence on complete root coverage (CRC) achieved by periodontal plastic techniques in the treatment of Miller class III/RT2 gingival recessions, comparing techniques developed along the twentieth century (pre-twenty-first) versus surgical approaches of the twenty-first century (21st).

Methods: An electronic bibliographic search was carried out in four databases up to December 2019, focusing on studies that reported CRC results in Miller class III or RT2 recessions treatment with at least a six-month follow-up. In addition, a random-effects models' meta-analysis was performed for the CRC, comparing pre-twenty-first versus twenty-first century techniques at 6 months, 12 months and more than 12 months.

Description of the modified vestibular incision subperiosteal tunnel access (m-VISTA) technique in the treatment of multiple Miller class III gingival recessions: a case series.

Background: Gingival recession is a common finding in the adult population. It is considered a challenge for clinicians to obtain a complete root coverage of Miller class III recession. The aim of this case series was to assess the outcomes achieved with the use of modified VISTA technique (m-VISTA) in patients having multiple Miller class III recessions after 6 months.

Treatment of Amalgam Tattoo With a New Technique: Mucoabrasion and Free Connective Tissue Graft.

Introduction: A new technique was performed for the removal of an amalgam tattoo (AT), consisting in mucoabrasion combined with a free connective tissue graft (FCTG).

Case Presentation: A 59-year-old female presented with a large AT involving the alveolar mucosa and gingiva between teeth #7 and #8, where endodontic treatment and apicoectomy was performed 21 years ago. To avoid compromising esthetics, the lesion was managed with a new technique including mucoabrasion and an FCTG.

One-year results of a nonsurgical treatment protocol for peri-implantitis. A retrospective case series.

Objectives: The aim of this study was to assess the clinical outcomes of a nonsurgical treatment protocol for peri-implantitis and to evaluate the influence that some factors could have on the results of this treatment.

Material And Methods: In this retrospective case series, patients with at least one implant with peri-implantitis, treated with a nonsurgical protocol and with a one-year follow-up, were included. Clinical parameters (probing depth, recession, bleeding, and/or suppuration on probing) were collected at baseline, 6 weeks, 3, 6, and 12 months.

Current understanding of genetic polymorphisms as biomarkers for risk of biological complications in implantology.

Background: In the last decade, multiple studies have been published that analyze the relationship between the risk of experiencing biological complications with implants and the presence of certain types of genetic polymorphisms. In the present report, we analyze the controversies that have arisen from this important area of investigation and synthesize the most prominent aspects of knowledge related to this possible etiopathogenic relationship.

Material And Methods: For this review, the biomedical databases PubMed-Medline, SciELO, and DOAJ were used.

Complications of harvesting a connective tissue graft from the palate. A retrospective study and description of a new technique.

Background: Connective tissue graft (CTG) is considered as the gold standard for the treatment of gingival recessions (GR). There are few studies assessing the complications that can arise in the donor site when harvesting a connective tissue graft (CTG) and how the harvesting technique can influence those complications.

Material And Methods: A retrospective clinical study was carried out in order to compare the complications observed in 40 patients with Miller class I, II and III GR ≥ 3 mm, after using the trap-door technique (TD) in the control group and a newly described technique, the "UPV/EHU technique", in the test group.

Histologic and Clinical Study of Gingival Recession Treated with Subepithelial Connective Tissue Graft: A Case Report.

Subepithelial connective tissue graft (SCTG) is considered the gold standard for treatment of gingival recessions. For ethical reasons, most studies report only clinical and not histologic results. A 20-year-old woman presenting with a localized gingival recession of 5 mm in the mandibular left central incisor was treated with SCTG.

Prevalence of peri-implant inflammatory disease in patients with a history of periodontal disease who receive supportive periodontal therapy.

Objectives: To describe the status of implants in periodontally compromised patients who regularly receive supportive periodontal therapy (SPT) and to determine the factors associated to peri-implant inflammatory disease in those patients.

Material And Methods: Clinical and radiographic data of implants in periodontal patients who, after being treated and included in a SPT programme, wore implant prostheses for at least 6 months were recorded. The implants were classified according to the criteria of the 6th European Workshop on Periodontology in health, mucositis and peri-implantitis.

Supportive periodontal therapy and periodontal biotype as prognostic factors in implants placed in patients with a history of periodontitis.

Objective: To evaluate bone loss around implants placed in patients with a history of treated chronic periodontitis and who did or did not attend supportive periodontal therapy, after one year in function. Furthermore, the influence of periodontal biotype and level of plaque was also evaluated.

Material And Methods: Forty-nine patients participated voluntarily in the study.

Immediate temporary restoration of single-tooth implants: Prospective clinical study.

Purpose: The goal of this study is to assess the survival, marginal bone loss and complications around single-tooth implants on which immediate provisionalization was carried out.

Patients And Methods: 78 implants were placed in 57 patients: 56 after extraction and 22 in healed sockets. Immediately after surgery provisional crows were delivered without contacts in both centric and excursive jaw movements.
