A passive fifi t is an important pre requisite for the long-term success of an abutment-based framework designs and prostheses, limiting the amount of stress transferred to the boneimplant interface. Yet, achieving a reliable passive insertion of a screw-retained metal framework on every case remains one of the most challenging areas in implant dentistry today for practitioner and technician alike.
In prosthesis with attachments, the initial project and the evaluation of the spaces play a fundamental part in the success of the rehabilitation. Providing for the insertion of the implants after these evaluations is fundamental. The dental technician often needs to manage complex situations and intervenes only once all is done, and at other times he must manage cases with old implants, while always keeping an eye on the containment of costs. The position of the implants can already determine the choice of prosthesis with mixed or pure implant support.
The first appointment with the patient has the purpose to record the desires and expectations of the subject as a basis for the treatment plan. The report, including the radiographic evaluations and basic CMD diagnostics, highlighted the following anomalies.
Implantology definitely occupies a strategically important role in the daily work of a laboratory and cases occur every day in which dental technicians need to create structures that can be of considerable magnitude (Toronto bridge, implant bridge etc...) or small entity interventions such as fabricating prosthesis of individual elements on implants. Today more than ever, we need to be able to provide optimal reconstructions in the creation of a single element as well as in full mouth rehabilitations.
In our case study, a female patient, in her mid-60’s, had two implants placed on numbers 6 and 11. The author/ clinician was challenged to give the best possible esthetics for her case. She wanted – brighter than her natural lower anterior teeth – with very little
in the way of characteristics. And when she smiled, she wanted to see life-like restorations.
This article will demonstrates a modern technological direction regarding how to create the best possible esthetics for your patients, using digital technology, step-by-step.
In the past, digitally-assisted production of implant-borne prosthetic restorations – without a suitable interface solution - has been an enormous challenge. This was, to a
lower extent, due to the process of digital impression using an intraoral scanner and a suitable scan body, rather than to a lack of availability of implant analogs suitable for CAM and of a digital master model; although these are the base of a precision produced implant restoration and, therefore, indispensable.
Treatment of the edentulous patient with the aid of dental implants has been a significant challenge for the treating clinician.
One of the patient concerns has been the reluctance to wear a denture during the transitional phase. Immediate loading has improved patient acceptance by providing patients with teeth the same day as the implant surgery. One significant issue has been breakage of the implant provisional restoration as a result of the increased forces that are attainable with implant supported restorations
Full acrylic dentures include full dentures, as well as overdentures and hybrid dentures. In all cases, a plastic material based on acrylic resin is used to restore the soft tissue and fabricate artificial teeth.
Our author José María Fonollosa demonstrates just how important a role lingualized occlusion can play in implant-supported full dentures.
The term overdentures refers to removable partial or full dentures that are placed over one or more remaining teeth, tooth roots or osseointegrated implants.
As a result of the remarkable increase in people’s expectations in the more developed nations during recent years, patient requirements for full dentures are now different compared to their expectations in the last century. In fact, these patients enjoy good health, their educational achievement is quite high, they perceive themselves as much younger than their date of birth would suggest (also confirmed by the increased use of anti-aging drugs and cosmetics), and they enjoy an intense social life.
How many patients agonise over their badly fitting prosthesis? No one knows for
sure. The patient in the case that we present was, however, no longer willing to accept the insecure grip and poor function of their previous restoration, and decided to seek out a recommended dental practice and find out more about the advantages of implants and he possibility of a stable dental placement solution. In a joint discussion, both the dentist and dental technician recommended a bar prosthesis. To this end, four implants
would need to be inserted in the front f the lower jaw and provide the basis or a bar to be screwed onto this. The new dentures could then be anchored o this bar by means of bar retention lips. Such a structure would provide a secure grip in all situations and would also be easily maintainable.
Advanced implantology techniques became common in the dental market as a solid part in the treatment planning, both on total and partial or single edentulous patients (Figures 1,2).
Focusing on total edentulousness patients, implant treatment is today the first rehabilitation procedure. Modern implantology has now the aim to support the edentulous patient (already carrier of a complete removable prosthesis or presenting a remaining compromised denture situation) with a fixed prosthesis therapy.
