Clinical course of patients with episodic cluster headache treated with corticosteroids inproximity to the sphenopalatine ganglion: a preliminary study of 23 patients.

Objective: A study is made of the clinical course of patients with episodic cluster headache following the injection of corticosteroids in the proximity of the sphenopalatine ganglion of the affected side.

Study Design: A retrospective observation study was made corresponding to the period between 2006 and 2010. Patients with episodic cluster headache received corticosteroid infiltrations in the vicinity of the sphenopalatine ganglion.

Maximum use of the anterior maxillary buttress in severe maxillary atrophy with tilted, palatally positioned implants: a preliminary study.

Purpose: To evaluate an alternative treatment for rehabilitation of the atrophic maxilla with palatal and tilted implants and to assess patient satisfaction with the results.

Materials And Methods: A retrospective case study was made of completely edentulous subjects with tilted, palatally positioned implants in the anterior maxillary buttress placed and loaded between January 2005 and January 2007. Patients with severely resorbed edentulous maxillae (Class V according to Cawood and Howell) who requested overdentures and were followed for 12 months after implant loading were included.

Dental implants placed simultaneously with bone grafts in horizontal defects: a clinical retrospective study with 37 patients.

Purpose: The aim of this study was to evaluate the 1-year success rate and marginal bone loss for dental implants placed simultaneously with bone grafts.

Materials And Methods: The study sample comprised 37 patients treated with dental implants placed simultaneous with intraoral block bone grafts. The block grafts were harvested from the chin, retromolar area, or maxillary tuberosity.

Retrospective study of 68 implants placed in the pterygomaxillary region using drills and osteotomes.

Purpose: The aim of this study was to evaluate the success rate of implants placed in the pterygomaxillary region using drills and osteotomes with a minimum of 12 months' follow-up. Bone loss after 1 year of loading and patient satisfaction with the prosthesis were evaluated.

Material And Methods: A retrospective case study was made.

Palatal positioning of implants in severely resorbed edentulous maxillae.

Purpose: The aim of this study was to evaluate implant-supported restorations supported by palatally positioned implants as an alternative treatment for rehabilitation of the atrophic maxilla and to assess the satisfaction of patients with the results.

Materials And Methods: A retrospective case study was conducted on completely edentulous subjects who received palatally positioned implants (placed and loaded) between January 2000 and January 2004. Inclusion criteria were patients with severely resorbed edentulous maxillae (Class IV or V maxillary atrophy, according to the Cawood and Howell classification) who requested implant-supported restorations and had a follow-up period of at least 24 months after implant loading.

Immediate implants after the removal of maxillary impacted canines: a clinical series of nine patients.

Purpose: When impacted maxillary canines are not amenable to orthodontic traction or reimplantation, extraction is the only solution available, followed by the option of implant placement. The aim of this study was to present a surgical technique that allows placement of immediate implants following extraction of impacted maxillary canines.

Materials And Methods: Included in the study were patients with impacted maxillary canines who refused orthodontic treatment or transplantation and/or in whom the position of the canine teeth did not allow fenestration and orthodontic traction.

Immediate loading of immediate mandibular implants with a full-arch fixed prosthesis: a preliminary study.

Purpose: To determine the survival of immediate dental implants with immediate loading in the partially edentulous mandible, by use of a full-arch screw-retained provisional restoration.

Materials And Methods: Patients who were partially edentulous in the mandible with indications for extraction of the remaining teeth and with a minimum follow-up of 12 months after implant placement were included in the study. They were treated in chronologic order by the insertion of 6 Defcon dental implants (Impladent, Sentmenat, Spain) subjected to immediate loading (4 interforaminal and 2 posterior placements).

Computer-guided implant placement in a patient with severe atrophy.

Computer software associated with imaging techniques facilitates diagnosis, planning, and management in cases of severe maxillary atrophy, by reducing the incidence of complications and improving the postoperative course and functional outcome. This article reports on a case of a 66-year-old woman with maxillary atrophy. Computer software was used to plan and position 6 maxillary and 4 mandibular implants, taking maximum advantage of the remaining bone.

Marginal bone loss in dental implants subjected to early loading (6 to 8 weeks postplacement) with a retrospective short-term follow-up.

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.

Level of satisfaction in patients with maxillary full-arch fixed prostheses: zygomatic versus conventional implants.

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) and those with no zygomatic implants (the nonzygomatic group).

Early loading of 642 Defcon implants: 1-year follow-up.

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 receiving 1 or more implants placed and loaded early between 2002 and 2005. The definition of implant success was based on clinical and radiologic Buser's criteria; all patients had a follow-up period of 1 year.

Rehabilitation of severely atrophic maxillae with fixed implant-supported prostheses using zygomatic implants placed using the sinus slot technique: clinical report on a series of 21 patients.

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 Methods: A retrospective chart review was conducted of all patients who received zygomatic implants between January 2000 and January 2005.
