Atom Transfer Radical Polymerisation (ATRP) has been used to polymerise ammonium 2-sulfatoethyl methacrylate (SEM) in aqueous media using various poly(ethylene glycol) (PEG) macro-initiators to give a range of controlled-structure, sulfate-based block copolymers. Such PEG–SEM diblock copolymers are effective crystal habit modifiers for the in situ(More)
PURPOSE This study was conducted to relate the histological diagnosis of chronic inflammatory periapical lesions with the radiographic images of these lesions. MATERIALS AND METHODS A total of 70 biopsy specimens obtained during periapical surgery were stained with hematoxylin and eosin and examined under a microscope. Histological analysis established(More)
PURPOSE The purpose of this article is to describe the management of patients with extreme maxillary atrophy. Their treatment consisted of maxillary fixed prostheses supported by conventional implants placed in residual anatomic structures in conjunction with zygomatic implants positioned using the sinus slot technique of Stella and Warner. MATERIALS AND(More)
PURPOSE Periapical surgery eliminates the periradicular inflammatory tissue and seals the apical foramen. The present study relates the radiologic size of the periapical lesion, apical resection, and retrograde filling to the middle- and long-term success of periapical surgery. MATERIALS AND METHODS In a prospective study, 235 patients and 333 teeth were(More)
PURPOSE Periapical surgery is followed by manifestations such as pain and swelling, the magnitude of which depends on the degree of tissue damage produced. A study is made of pain and inflammation in the 7 days after periapical surgery and its relation to patient age, gender, smoking, oral hygiene, the location and number of teeth implicated, the duration(More)
PURPOSE To evaluate the success rate and marginal bone loss in dental implants loaded after 8 weeks in the maxilla and after 6 weeks in the mandible, after 1 year of follow-up. MATERIALS AND METHODS A retrospective case series study was made. The sample was composed of subjects having 1 or more implants placed and loaded early between 2004 and 2006.(More)
PURPOSE To evaluate the satisfaction of patients with maxillary fixed prostheses supported by conventional and/or zygomatic implants. MATERIALS AND METHODS Patients restored with complete maxillary implant-supported fixed prostheses were included in the study. They were divided into 2 groups: those with at least 1 zygomatic implant (the zygomatic group)(More)
OBJECTIVES To evaluate pain and swelling during the first week after periapical surgery and its relation to patient age, gender, oral hygiene, and smoking. STUDY DESIGN One hundred two patients (31 men and 71 women) with a mean age of 40.2 years underwent periapical surgery. Age, gender, and oral hygiene and cigarette smoking before and during the(More)
INTRODUCTION A multidisciplinary approach with several specialits allows a complete treatment for Cleft Lip and Palate. We show our experience in presurgical orthopedic treatment in these patients, their advantages, their problems and the results. MATERIAL AND METHODS Since 1999 presurgical orthopedy has been applied to 12 patients (3 bilateral cleft lip(More)
PURPOSE This study estimated the 1-year survival of early-loaded Defcon treatment surface Avantblast (TSA) implants (Impladent; Sentmenat, Barcelona, Spain) and compared this success rate with those reported in the literature for conventionally loaded implants. MATERIALS AND METHODS In this retrospective case series study, the sample comprised subjects(More)
