Long-Term Clinical Outcomes of Treatment with Dental Implants with Acid Etched Surface

Abstract

Implant dentistry constitutes a therapeutic modality in the prosthodontic treatment of partially and totally edentulous patients. This study reports a long-term evaluation of treatment by the early loading of acid-etched surface implants. Forty-eight partially and totally edentulous patients were treated with 169 TSA Defcon® acid-etched surface implants for prosthodontic rehabilitation. Implants were loaded after a healing free-loading period of 6–8 weeks in mandible and maxilla, respectively. Implant and prosthodontic clinical findings were followed during at least 17 years. Clinical results indicate a survival and success rate of implants of 92.9%, demonstrating that acid-etched surface achieves and maintains successful osseointegration. Five implants in three patients were lost during the healing period. Sixty-five prostheses were placed in 45 patients over the remaining 164 implants, 30 single crowns, 21 partially fixed bridges, 9 overdentures, and 5 full-arch fixed rehabilitations. A total of 12 implants were lost during the follow-up period. Mean marginal bone loss was 1.91 ± 1.24 mm, ranging from 1.1 to 3.6 mm. The most frequent complication was prosthetic technical complications (14.2%), followed by peri-implantitis (10.6%). The mean follow-up was of 214.4 months (208–228 months). Prosthodontic rehabilitation with an early-loading protocol over acid-etched surface implants is a successful implant treatment.

Fixed Prosthetic Restorations With Sandblasted Surface Implants: Long-term Results of a Clinical Study

“…Nowadays, most of the implants are moderately rough, and their surfaces have been treated by sandblasting, acid-etching, anodization, or other techniques. Long-term studies have reported excellent outcomes on treatments performed with rough implant surfaces [19,20].…”

La eficacia clínica a largo plazo de los implantes con conexión interna y superficie arenada y grabada

“…Los implantes de conexión interna pueden obtener una excelente fijación y transmisión de fuerzas de los pilares a los implantes. Estos hallazgos clínicos son confirmados por el presente estudio, donde los im-plantes utilizados presentaban una conexión interna para su unión a los correspondientes pilares protésicos [18][19] . Un aspecto importante, también del diseño de los implantes utilizados en este estudio es que presentaban en su diseño una plataforma reducida o platform switching.…”

“…Los estudios a largo plazo indican que la fase de mantenimiento debe incluir las revisiones periódicas del tratamiento con implantes y debe basarse en una colaboración permanente entre el profesional y el paciente 19 . El profesional debe conocer la longevidad de las intervenciones quirúrgicas y prostodóncicas realizadas, y previamente al comienzo del tratamiento informar al paciente e incluir esta información en el consentimiento informado [20][21] .…”

Mineralization of Titanium Surfaces: Biomimetic Implants

“…Some implant brands use acid etching to create negative charges on the surface that prevent their migration through immersion in a polar solvent, such as water (Straumann SLA Active), or implant grit blasted with calcium phosphate particles (bioactive) so that residue on the surface helps to generate new bone around the dental implant (Osseotite); others change topographies with a certain porosity of the titanium oxide of the passivation on the surface, exerting high values of passivating potential generated by etching [ 18 , 19 ]. The designed modification consists of etching by NaOH to produce a modification in the titanium oxide (only in the uppermost part of the passivation layer) by forming sodium titanate, which produces a negative charge on the surface.…”
