Complications of guided surgery and immediate loading in oral implantology: a report of 12 cases

Objectives: The growing interest in minimally invasive surgery, together with the possibility of fitting prostheses with immediate function, have led to the development of software capable of planning and manufacturing a surgical guide and prosthesis that can be placed upon conclusion of the implant surgery step. The present study evaluates the surgical and prosthetic complications of implant treatment with the guided surgery technique, together with patient comfort during and after treatment. Patients and methods: A retrospective observational study was made of 19 patients with partially or totally edentulous upper and/or lower maxillae, involving the placement of a total of 122 implants. All cases were planned and operated upon with the guided surgery technique. Results: A total of 122 implants were placed in 14 males and 5 females. The intraoperative surgical complications comprised a lack of primary stability, while the postoperative complications consisted of infections and a lack of implant osteointegration. Ten implants failed. The prosthetic complications in turn comprised loosening of the provisional prosthesis screws, prosthesis tooth fracture, and a lack of passive fit of the immediate prosthesis. The degree of patient satisfaction was evaluated using a verbal scale. Conclusions: Implant restoration with the guided surgery technique and immediate functional loading is a predictable procedure, provided patient selection and the surgical technique are adequate, affording lesser postoperative morbidity and increased patient satisfaction thanks to the immediate restoration of esthetics and functio

The late Neogene-early Quaternary small vertebrate succession from the Almenara-Casablanca karst complex (Castellón, Eastern Spain): Chronologic and paleoclimatic context

Although discontinuous because of their karst nature, the Almenara-Casablanca complex records a very complete small vertebrate succession (amphibians, squamates, insectivores, bats, rodents and lagomorphs), characterized by the richness of their sites, a richness which cannot be expected in sites of fluvio-lacustrine origin. This late Neogene-early Quaternary succession includes the sites of Almenara- Casablanca M (Miocene-Pliocene boundary), Almenara-Casablanca 4 (late Pliocene), Almenara-Casablanca 1 (earliest Pleistocene) and Almenara-Casablanca 3 (late early Pleistocene). In this way, the Almenara-Casablanca succession complements the data from other well know terrestrial Pliocene- Pleistocene sequences in the Iberian Peninsula, most notably that of the Guadix-Baza Basin. The complementation between the almost continuous Pliocene-Pleistocene sequence of the Guadix-Baza Basin and the discontinuous but very rich succession from the Almenara-Casablanca complex enables accurate dating of some of the faunal events that punctuate the Pliocene-early Pleistocene time interval. Furthermore, the assemblages from the Almenara-Casablanca complex contain the evidence of the earliest occurrences of several taxa as well as the persistence of other that had already disappeared from other European regions. Therefore, it provides new evidence for the particular role which the Iberian Peninsula played during the late Neogene and early Quaternary, acting at certain moments as a bridge for the entry of African taxa or, alternatively, as a refuge for other European taxa. This paper provides an updated review of the small vertebrate succession from this complex
