Indications

Zygomatic implants have been documented as a an alternative for the rehabilitation of the atrophic posterior maxilla with both the classical two stage and immediate loading protocols. Zygomatic implants avoid grafting and sinus lift procedures and therefore contribut

The lecture reviews the principles of the rehabilitation of the extremely resorbed maxilla and compares Zygomatic implants with sinus lift and augmentation procedures, and highlights the importance of the Zygomatic concept for implantology. Under extreme clinical circumstances like...

Demand for quality performance measures is increasing in many professions, including medical and dental procedures. Patients, insurance providers and governments request reliable data for adequate evaluation of treatment procedures, medical device performance, treatment result...

The All-on-4 treatment concept has an impressive track record. Described by Branemark et al. in 1971, a 10 year follow up in 1975 reported no statistical differences in success rates between a 4 or 6 implant restoration. Dr Bedrossian presents a comprehensive recent literature...

For heavily resorbed maxilla situations, Zygomatic implants offer a graftless, minimally invasive surgery with immediate function treatment option. Dr Davo discusses available literature data and own clinical experience and concludes that this treatment has only a low rate of...

The lecture discusses in how far the assessment of marginal bone can be a suitable measure for bone integrity and implant oesseointegration. Dr Koka reviews aspects of definition of bone quality and the concept of osseo-sufficiency, and shows that we still are influenced by biases...

The rehabilitation of the resorbed jaw remains a surgical and prosthetic challenge. This may involve the modification of the bone to allow for placement of dental implants, or alternatively the use of short implants. EAO consensus defines short implants as implants with an intrabon

The lecture raises the discussion about overtreatment of natural teeth or alternatively also with implants. Dr Walton introduces his thoughts as a 'tale of caution'. Is ongoing treatment of severely structurally or periodontally compromised teeth - 'herodontics' - still justified...

The lecture reviews and compares a data pool with almost 40.000 implants placed in an over 20 year time period. Dr Laureen Langer concludes that there are high and equivalent survival rates and no statistical differences between immediate and delayed placement, and that the...

The lecture presents options how to rehabilitate the posterior maxilla and mandible in complex situations and discusses the use of short implants and vertical bone augmentation options. If possible, short implants are a preferred and less invasive option, however for anatomical or...

The tradition to insert 6 implants, and eventually more, in an arch-wide pattern dates back to the early days of osseointegration when implants with a machined surface were used and risk for early...

Traditional endosseous oral implant treatment protocols ad modum Brånemark required a variable healing period (usually 3-6 months) before prosthesis placement. The healing period was considered necessary to achieve osseointegration and establish a load-bearing interface...

Attachment selection

The relative merits of different prosthodontic treatment objectives - resilient versus rigid attachments - are controversial and empirical. A resilient retention mechanism is recommended on the assumption that this will protect implants from overload; while in...

In the atrophic mandible soft tissues become prominent and the inferior alveolar nerve is located more superficially.
Fractures of the atrophic edentulous mandible can occur during implant insertion. Especially in hard bone...

Focusing on the posterior mandible, Dr Moy reviews aspects of flap design and development, selection of implant design and dimensions, selection of the appropriate loading protocol and discusses the use of guided approach. Soft tissue management should maintain and enhance quality...
