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 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 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)
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)
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 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 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 This study compares periapical surgery (PS) of the maxillary premolars and molars in close proximity to the maxillary sinus with those not in close proximity, and assesses postoperative morbidity and prognosis. PATIENTS AND METHODS A prospective follow-up study was carried out on clinical cases of PS using the ultrasound technique. Only patients(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)
In recent years, periapical surgery has evolved thanks to new diagnostic and technical advances. A review is made of the literature on periapical surgery of the antral teeth, based on a Medline search and on the revision of Spanish dental journals in the period between 1974 and 2003. The anatomy of the maxillary sinus is discussed, along with the diagnosis(More)
