ABSTRACT
BACKGROUND: Narrow diameter implants (NDIs) are used in cases of limited mesio-distal space, or if the alveolar ridge does not allow placement of a standard diameter implant. PURPOSE: The aim of this prospective case series study is to present the 5-year clinical-, radiological-, and patient-reported outcome measures (PROMs) of patients with partial edentulism in the anterior area of the jaws requiring the placement of two narrow diameter implants to support a 3- or 4-unit fixed partial denture (FPD). MATERIALS AND METHODS: Thirty partially edentulous patients missing 3 or 4 adjacent teeth in the anterior area of the jaws were included in the study. Two titanium-zirconium tissue-level NDIs were placed in each patient in healed anterior sites (60 implants). A conventional loading protocol was performed to provide a FPD. Implant survival, success, marginal bone-level changes (MBL), clinical parameters, buccal bone stability with CBCT, adverse events and PROMs were recorded. RESULTS: The survival and success rates for the implants were 100%. The mean MBL (±SD) after prosthesis delivery, and 5-year follow-up (mean 58.8 months; range: 36-60) was 0.12 ± 0.22 and 0.52 ± 0.46 mm, respectively. Decementation and screw loosening were the most frequent prosthetic complications, yielding a prosthetic survival and success rates of 100% and 80%, respectively. Patient satisfaction was high with a mean (±SD) score of 89.6 ± 15.1. CONCLUSIONS: The use of tissue-level titanium-zirconium NDIs supporting splinted multi-unit FPDs in the anterior area seems to be a safe and predictable treatment option after a 5-year follow-up period.

The esthetics and emergence profile design of implant-supported restorations in the anterior zone can be challenging. This dental technique describes a digital approach to designing an optimal emergence profile from the implant head to the definitive prosthetic volume with facial cutback for an esthetic implant-supported interim crown. A printed interim implant-supported restoration with an adequate emergence profile and a facial cutback for composite resin layering is obtained.
ABSTRACT
Los dentistas y sus pacientes se enfrentan a menudo a difíciles decisiones de tratamiento. Una de las situaciones más complicadas puede ser decidir preservar un diente con un tratamiento de endodoncia o bien extraerlo y sustituirlo con un implante. Ambas opciones, endodoncia no quirúrgica seguida de una restauración adecuada, o el implante dental son opciones de tratamiento excelentes para el diente comprometido. Estas decisiones deben basarse en los resultados descritos en la literatura. Las revisiones de la literatura actual pueden arrojar una visión objetiva de la evidencia disponible que pueda ayudar a los dentistas y a sus pacientes a decidir la mejor opción de tratamiento (AU)
Dentists and patients are regularly confronted by difficult treatment questions. One of the major issues is the treatment decision between extracting a tooth with placement of a dental implant or preserving the natural tooth by means of root canal treatment. Both nonsurgical root canal therapy followed by an apropriate restoration and single-tooth implants are excellent treatment modalities for the treatment of compromised teeth. Treatment decisions must be taken based on scientific studies. A systematic review of the existing literature can provide with objective data and the best available evidence that can help dentists and their patients to take the best possible treatment (AU)
