Despite the increasing patients’ desire for immediate prosthetic loading of implants, several factors must be taken into account before pursuing the immediate loading (IL) protocol. In general, the number, size, characterization, and distribution of implants should be based on the implant-prosthodontic plan, arch form, and available bone quality an...

Current literature does not contribute to a high level of evidence regarding possible indications for immediate loading. A great variety of exclusion criteria for immediate loading of dental implants are used in different studies. However, the reported criteria are similar to those chosen for conventional loading of dental implants. Despite its sev...

Severe bone atrophy of the upper maxilla (Cawood and Howell class V and VI) is associated with certain problems such as reduced perioral tissue support, the impossibility of wearing complete dentures, chewing and speech alterations, and difficulties in placing dental implants due to the limited amount of available bone.

Dental implants can be integrated at both hard and soft tissue levels. Osseointegration is a dynamic process during its establishment and maintenance, characterized by resorption and apposition events, and the extent and degree of osseointegration is in part affected by implant surface configuration. It is marked by three distinct healing stages du...

The zygomatic fixture is an extended length (35–55 mm) titanium implant, placed into the zygomatic and maxillary alveolar bone. It was designed for situations where atrophy of the posterior maxilla complicates or prevents the placing of conventional implants. The use of zygomatic implants avoids the need for bone grafting, shortens treatment times,...

Brånemark traditional recommendation was to perform implant rehabilitation in two stages: the first entry was only for implant placement; after 3–6 months of undisturbed submerged healing for mandible and maxilla, respectively, a second surgical entry would have allowed loading of the implants. The rationale behind this approach was that implant mi...

Immediate loading is basically a prosthetic concept. However, the surgical implantological planning is very important to ensure a primary stability in the total edentulous patient. This characteristic is crucial to allow immediate loading in this type of patients. For the first time, the incisional design has allowed the clinician to overview about...
