Influence of periodontal maintenance and periodontitis susceptibility on implant success: A 5-year retrospective cohort on moderately rough surfaced implants.

Objectives: To investigate the effect of defined versus undefined periodontal maintenance after implant therapy on the prevalence of peri-implant complications.

Material And Methods: Two hundred patients who underwent dental implant therapy in the National Dental Centre Singapore (NDCS) from 2005 to 2012 were recruited. One hundred patients had regular periodontal maintenance (defined maintenance programme group, DMP), and the other 100 patients had no documentation of periodontal maintenance (undefined maintenance programme group, UMP).

The effect of systemic antibiotics on clinical and patient-reported outcome measures of oral implant therapy with simultaneous guided bone regeneration.

Objectives: The aim of the present superiority study was to determine the effect of systemic antibiotics primarily on patient-reported outcome measures (PROMs) and post-surgical complications in patients undergoing oral implant therapy with simultaneous guided bone regeneration (GBR).

Materials And Methods: A total of 236 medically and periodontally healthy patients received oral implants with simultaneous GBR at seven centres. Pre-operative antibiotics of 2 g amoxicillin were prescribed to the test group 1 hr prior to surgery and 500 mg thrice daily on days 1-3 after surgery.

Influence of maintenance care in periodontally susceptible and non-susceptible subjects following implant therapy.

Objectives: To compare the periodontal and peri-implant conditions of periodontally susceptible and periodontally healthy subjects under maintenance care for a period of at least 3 years.

Material And Methods: Sixty periodontally susceptible patients (PSP) and 56 periodontally non-susceptible subjects (PHS) were treated with dental implants in the National Dental Centre Singapore (NDCS) and were maintained in a regular supportive periodontal care program for a mean of 6 years. Full mouth bleeding on probing (BoP), full mouth probing pocket depths (PPD), implant loss, and absence of crestal bone loss were recorded at the time of prosthesis delivery and following a mean follow-up of 6 years 2 months.

Use of a collagen matrix for recession coverage in patients who received orthodontic therapy: a case series.

Aim: The aim of the present study was to determine the percentage of recession coverage achieved following surgery with a collagen matrix, and patient-reported outcome measures.

Methods: Five healthy adults who had completed orthodontic therapy with a gingival recession defect were recruited. Gingival recession coverage was performed using a two-layer, xenogeneic collagen matrix (Mucograft).

Patient-reported outcome measures after routine periodontal and implant surgical procedures.

Objectives: To compare patient-reported outcome measures (PROMs) after different dental surgical procedures over a 1-week post-surgical period and in relation to duration of the surgery, and periosteal releasing incisions. To evaluate the prevalence of post-surgical complications.

Material & Methods: Four hundred and sixty-eight healthy dental patients requiring surgeries, such as crown lengthening (CL), open flap debridement (OFD) and implant installation (IMP) in the National Dental Centre, Singapore (2009-2011), were consecutively recruited.

Effect of systemic antibiotics on clinical and patient-reported outcomes of implant therapy - a multicenter randomized controlled clinical trial.

Objectives: To determine the effect of various systemic antibiotic prophylaxis regimes on patient-reported outcomes and postsurgical complications in patients undergoing conventional implant installation.

Material And Methods: Three hundred and twenty-nine healthy adults in need of conventional implant installation were randomly assigned to one of four groups: (i) preoperatively 2 g of amoxycillin 1 h before surgery (positive control, PC), (ii) postoperatively 2 g of amoxycillin immediately following surgery (test 1, T1), (iii) preoperatively 2 g of amoxycillin 1 h before and 500 mg thrice daily on days 2 and 3 after surgery (test 2, T2), (iv) preoperatively 2 g of placebo 1 h before surgery (negative control, NC). Subjects were examined clinically by blinded examiners over 8 weeks after implant installation.

The effect of different implant neck configurations on soft and hard tissue healing: a randomized-controlled clinical trial.

Objective: to compare the soft and hard tissue healing and remodeling around tissue-level implants with different neck configurations after at least 1 year of functional loading.

Material And Methods: eighteen patients with multiple missing teeth in the posterior area received two implants inserted in the same sextant. One test (T) implant with a 1.

A systematic review of the success of sinus floor elevation and survival of implants inserted in combination with sinus floor elevation. Part II: transalveolar technique.

Objectives: The objectives of this systematic review were to assess the survival rate of implants placed in sites with transalveolar sinus floor elevation.

Material And Methods: An electronic search was conducted to identify prospective and retrospective cohort studies on transalveolar sinus floor elevation, with a mean follow-up time of at least 1 year after functional loading. Failure and complication rates were analyzed using random-effects Poisson regression models to obtain summary estimates/ year proportions.

A systematic review of the success of sinus floor elevation and survival of implants inserted in combination with sinus floor elevation.

Objectives: The objectives of this systematic review were to assess the survival rate of grafts and implants placed with sinus floor elevation.

Material And Methods: An electronic search was conducted to identify studies on sinus floor elevation, with a mean follow-up time of at least 1 year after functional loading.

Results: The search provided 839 titles.

A systematic review of the effects of full-mouth debridement with and without antiseptics in patients with chronic periodontitis.

Objectives: To assess the clinical and microbiological effects of full-mouth debridement with (FMD) and without the use of antiseptics [full-mouth scaling and root planing (FMSRP)] in comparison with conventional staged debridement (CSD) in patients with chronic periodontitis after at least 6 months.

Material And Methods: The search in MEDLINE (PubMed), covering a period of 1975 to October 2007, and hand searching yielded 207 titles. Forty-two abstracts and 17 full-text articles were screened for inclusion.

A systematic review of the survival and complication rates of resin-bonded bridges after an observation period of at least 5 years.

Objectives: The objectives of this systematic review were to assess the 5-year survival of resin-bonded bridges (RBBs) and to describe the incidence of technical and biological complications.

Methods: An electronic Medline search complemented by manual searching was conducted to identify prospective and retrospective cohort studies on RBBs with a mean follow-up time of at least 5 years. Patients had to have been examined clinically at the follow-up visit.

Diabetes as a risk factor for periodontal disease: current status and future considerations.

Introduction: Over the past decade, there has been an emerging interest in the interrelationship between systemic conditions and oral health. Diabetes is perhaps one of the best documented conditions that have been closely linked with periodontal disease. This paper reviews the role of diabetes as a risk factor in periodontal disease.
