Retrospective analysis of survival rates and marginal bone loss on short implants in the mandible
2011
Objectives: Short implants have become an interesting alternative to bone augmentation in dental implantology. Design of shorter implants and longer surveillance times are a current research issue. The goal of this study was to show the survival rates of short implants below 9 mm in the partly edentulous mandibular premolar and molar regions with fixed prosthetics. Marginal vertical and 2D bone loss was evaluated additionally. Different implant designs are orientationally evaluated. Material and Methods: A total of 247 dental implants with fixed prosthetics (crowns and bridges) in the premolar and molar region of the mandible were evaluated; 47 implants were 9 mm or shorter. Patient data we…
Immediate Implant Placement in Fresh Mandibular Molar Extraction Socket: 8-Year Results. A Case Report
2010
Abstract Recently, successful implant placement in fresh extraction sockets has been reported. In this case report, we present the results of an immediate implant placement in a fresh extraction socket of a mandibular molar with simultaneous bone regeneration using a nonresorbable membrane and no other graft materials. Clinical and radiographic findings acquired 8 years after implant placement demonstrated a stable peri-implant situation and confirmed a satisfactory treatment result.
Descriptive retrospective study analyzing relevant factors related to dental implant failure
2019
Background The objective of this retrospective descriptive study was to analyze the characteristics of incident reports provided by dentists while using a specific brand of dental implants. Material and Methods The study was carried out in collaboration with Oxtein Iberia S.L.®, with the company providing access to the incident database in order to evaluate the characteristics of incidents from January 2014 to December 2017 (a total of 917 over four years). The data sheet recorded different variables during each of the stages of implant treatment, from initial implant placement to subsequent prosthetic rehabilitation. These variables included age, sex, systemic pathologies, smoking habits, …
Implant treatment in atrophic posterior mandibles: Vertical regeneration with block bone grafts versus implants with 5.5-mm intrabony length
2014
Purpose: To retrospectively compare the outcomes of implants placed in posterior mandibles vertically regenerated with onlay autogenous block bone grafts and short dental implants. Materials and Methods: Consecutive patients with vertical bone atrophy in edentulous mandibular posterior regions (7 to 8 mm of bone above the inferior alveolar nerve) were treated with either implants placed in regenerated bone using autologous block bone grafts (group 1) or short implants (with 5.5-mm intrabony length) in native bone (group 2) between 2005 and 2010 and followed for 12 months after loading. The procedure used was the established treatment protocol for this type of patient at the Oral Surgery Uni…
Prevalence of complications after the oral rehabilitation with implant-supported hybrid prostheses
2010
Objectives: Assess the main problems referred by the patients and observed by the professionals after the bucodental rehabilitation with an implant-supported hybrid prothesis. Patient and Methods: A retrospective study was carried out in which there were 43 patients included who were visited in the Department of Oral Surgery and Orofacial Implantology of University of Barcelona Dental School for one year. An oral rehabilitation with an implant-supported hybrid prosthesis was made to those patients. The following variables were registered: age, gender, number of inserted implants, type of implant and principal problems produced by the hybrid prosthesis. Results: The rehabilitation with an im…
Placement of endosseous implants in patients with oral epidermolysis bullosa.
2000
Abstract Objective: To evaluate the feasibility of placing endosseous implants in patients with recessive dystrophic epidermolysis bullosa. This article reports on 4 patients subjected to follow-up. Study Design: Implants were placed in 4 cases. All patients have marked oral involvement, with devastating alterations in the soft and hard tissues in all cases. Results: A total of 15 implants (7 maxillary, 8 mandibular) were placed. All implants integrated successfully and have been restored. The average follow-up from implant placement was 2.5 years (range, 1-4). Conclusions: Our preliminary findings suggest that endosseous implants can be successfully placed and can provide support for prost…
Implants in free fibula flap supporting dental rehabilitation - Implant and peri-implant related outcomes of a randomized clinical trial.
2016
Abstract Objectives The objective of this study was to assess the difference in success rates of implants when using two or four implant-supported-overdentures following segmental mandibular reconstruction with fibula free flap. Methods and designs This prospective, parallel designed, randomized clinical study was conducted with 1:1 ratio. At baseline, all participants already had segmental reconstruction of mandible with free fibula flap. The participants were randomized into two groups: Group-I received implant-supported-overdentures on two tissue-level implants and Group-II received implant-supported-overdentures on four tissue-level implants. Success rates of the implants were evaluated…
An up to 7-Year Retrospective Analysis of Biologic and Technical Complication With the All-on-4 Concept
2016
The aim of this study was to evaluate retrospectively biologic and technical complications as well as clinical and radiographic outcomes of patients treated with 4 implants according to the All-on-4 protocol and followed up to 7 years of function. Data from 56 consecutive patients presenting complete edentulous jaw, aged 18 years or older, treated between January 2008 and December 2013, were evaluated. The outcomes were implant and prosthetic survival and success rates, any complications, and marginal bone loss (MBL). Two-hundred twenty-four implants were placed in 56 patients. During the entire follow-up, 1 maxillary implant but no prosthesis failed during the healing process. Fourteen pat…
Five-Year Study of Implant Placement in Regenerated Bone and Rehabilitation With Telescopic Crown Retained Dentures: A Case Report
2009
Abstract Various implant-supported restorations have been used successfully for several decades to rehabilitate edentulous patients. Telescopic crowns are a common treatment modality used to connect dentures to natural teeth. Although previous findings indicate that telescopic crowns can be placed successfully on implants to support overdentures, only limited data are available on this treatment approach. Eight months after extraction of all nonsalvageable teeth and socket preservation, 11 implants were inserted into the mandible and maxillae of one patient. These implants were restored 4 months later using telescopic crown–supported dentures. Bleeding on probing (BOP), plaque index (PI), c…
Masticatory muscle activity evaluation by electromyography in subjects with zygomatic implants
2017
Background Zygomatic implants are an alternative treatment in the rehabilitation of atrophic maxilla to promote stability in the stomatognathic system. The aim of this study was to compare the electromyographic (EMG) activity of masseter and temporalis muscles in controls and in individuals with complete implant-supported dentures anchored in the zygomatic bone. Material and Methods Fifty-four volunteers of both genders (mean age 52.5 years) were selected and distributed into two groups: Individuals with zygomatic implant (ZIG; n=27) and fully dentate patients (CG; n=27). MyoSystem-BR1 was used to assess masseter and temporalis muscles EMG activity in different mandibular movements: protrus…
