Virtual articulator for the analysis of dental occlusion: An update
2010
The future of dental practice is closely linked to the utilization of computer-based technology, specifically virtual reality, which allows the dental surgeon to simulate true life situations in patients. The virtual articulator has been designed for the exhaustive analysis of static and dynamic occlusion, with the purpose of substituting mechanical articulators and avoiding their errors. These tools will help both odontologists and dental prosthetists to provide the best individualized treatment for each patient. The present review analyzes the studies published in the literature on the design, functioning and applications of virtual articulators. A Medline-PubMed search was made of dental…
Risk factors associated with early failure of dental implants. A literature review
2010
The aim of the study was to examine articles published on risk factors associated with early failure of dental implants. We conducted a search on PubMed for articles published between January 2000 and December 2009 using the keywords 'dental implants' and 'early failure'. Seven studies that specified the number of early failed implants and studied the associated risk factors were included. Early failures are caused by the inability of tissue to establish osseointegration prior to prosthetic restoration; however the causal factors and mechanisms are unclear. In the reviewed literature there was a higher percentage of early than late failures; nevertheless, few articles were found that analyz…
Aluminum Chloride versus Electrocauterization in Periapical Surgery: A Randomized Controlled Trial
2019
The aim of this study was to evaluate the efficacy of 2 hemostatic agents in periapical surgery and its relationship with patient- and tooth-dependent variables.A prospective study was designed with 2 randomized parallel groups established according to the hemostatic agent used: aluminum chloride or electrocauterization. The surgeon and 2 independent blinded observers examined the initial and final bleeding and recorded it as 0 (no hemorrhage control), 1 (slight but apparent intermittent bleeding), or 2 (complete hemorrhage control). The following patient- and tooth-dependent variables were collected: sex, age, smoking habit, plaque index, and position.Sixty patients with a periapical lesio…
Implant periapical lesion: diagnosis and treatment
2011
The implant periapical lesion is the infectious-inflammatory process of the tissues surrounding the implant apex. It may be caused by different factors: contamination of the implant surface, overheating of bone during drilling, preparation of a longer implant bed than the implant itself, and pre-existing bone disease. Diagnosis is achieved by studying the presence of symptoms and signs such us pain, swelling, suppuration or fistula; in the radiograph an implant periapical radiolucency may appear. A diagnostic classification is proposed to establish the stage of the lesion, and determine the best treatment option accordingly. The following stages are distinguished: acute apical periimplantit…
Oromandibular dystonia: A dental approach
2010
Oromandibular dystonia consists of prolonged spasms of contraction of the muscles of the mouth and jaw. Primary idiopathic forms and secondary forms exist. Secondary dystonia develops due to environmental factors; some cases of cranial dystonia after dental procedure have been reported, but the causal relationship between these procedures and dystonia remains unclear. Traumatic situations in the mouth, such as poor aligned dentures or multiple teeth extractions may cause an impairment of proprioception of the oral cavity, leading to subsequent development of dystonia. The clinical characteristics of oromandibular dystonia are classified according to the affected muscles. The muscles involve…

Objective: To assess pain and swelling in the first 7 days after periapical surgery and their relationship with the agent used for bleeding control. Study Design: A prospective study was conducted between October 2006 and March 2009. Patients subjected to root surgery, who completed the questionnaire and who consented to the postoperative instructions were included in the study. The subjects were divided into two groups according to the hemostatic agent used: A) gauze impregnated with anesthetic solution with vasoconstrictor; or B) aluminum chloride. The patients were administered a questionnaire, and were asked to record the severity of their pain and swelling on a plain horizontal visual …
Maxillary sinus septa : A systematic review
2008
This review analyzes articles published on the presence of septa in maxillary sinuses. An automated search was conducted on PubMed using different key words. This search resulted in 11 papers in which the presence of antral septa was assessed. These septa are barriers of cortical bone that arise from the floor or from the walls of the sinus and may even divide the sinus into two or more cavities. They may originate during maxillary development and tooth growth, in which case they are known as primary septa; or they may be acquired structures resulting from the pneumatization of maxillary sinus after tooth loss, in which case they are called secondary septa. Several methods have been used in…
Bone regeneration using particulate grafts : an update
2010
Objective: A review is made of the publications on bone regeneration using particulate grafts, with an evaluation of the success of implants placed in such regenerated areas. Material and Method: A Medline search using different key words was made of the articles published between 1999-2009 involving at least two patients subjected to grafting with autologous, homologous or xenogenic bone, non-bony substitutes, or a combination of these grafts for the placement of dental implants. Studies involving block grafting were excluded. A total of 11 studies were evaluated. Results: These grafts are indicated in cases of small or peri-implant bone defects such as dehiscences and fenestrations, with …
Hemostatic Agents in Periapical Surgery: A Randomized Study of Gauze Impregnated in Epinephrine versus Aluminum Chloride
2016
Abstract Introduction Adequate bleeding control is essential for the success of periapical surgery. The aim of this study was to evaluate the effects of 2 hemostatic agents on the outcome of periapical surgery and their relationship with patient and teeth parameters. Methods A prospective study was designed with 2 randomized parallel groups, depending on the hemostatic agent used: gauze impregnated in epinephrine (epinephrine group) and aluminum chloride (aluminum chloride group). The analysis of the hemorrhage control was judged before and after the application of the hemostatic agents by the surgeon, and 2 examiners independently recorded it as adequate (complete hemorrhage control) or in…
Survival of implants placed with the osteotome technique : an update. Review
2012
A literature review is made to analyze the survival of implants placed with the osteotome technique. A PubMed search was made based on the key words “osteotome AND dental implants”, corresponding to publications between 1998-2008. The inclusion criteria were: a) a minimum of 10 patients; b) a minimum follow-up of 6 months; c) implants placed using the osteotome technique with or without indirect sinus lift; and d) specification of the implant number and survival rate. Sixty-four articles were identified, of which 20 met the inclusion criteria. A total of 2006 implants were placed in 1312 patients using the osteotome technique. The duration of follow-up after prosthetic loading ranged from 6…
Influence of Hemostatic Agents in the Prognosis of Periapical Surgery: A Randomized Study of Epinephrine versus Aluminum Chloride
2017
Abstract Introduction Several variables have been associated with a better prognosis of periapical surgery. The aim of this study was to evaluate the influence of 2 hemostatic agents on the prognosis of periapical surgery at 12 months. Methods A prospective study was designed with 2 randomized parallel groups established depending on the hemostatic agent used: epinephrine or aluminum chloride. The analysis of the hemorrhage control was recorded as 0 (no hemorrhage control), 1 (slight but apparent intermittent bleeding persisted after application of the material), or 2 (complete hemorrhage control). At 12 months, periapical lesion healing was determined clinically and radiologically as succe…
