All-on-4 refers to a treatment concept in which four implants support a fixed full-arch restoration. The number describes the implants supporting one arch. It does not describe four pairs of implants or a separate implant for every replacement tooth.
What the treatment name establishes
Nobel Biocare's treatment description identifies a full-arch concept on four implants. Its immediate-loading option depends on patient criteria and adequate stability. A treatment name therefore does not establish that an individual patient can receive a functioning bridge on a particular day.
Have the dentist identify the proposed restoration and the components supporting it. The multi-unit abutment guide explains one intermediate component used in full-arch systems.
Record the temporary and final stages
Ask which restoration will be delivered first, what it is intended to do and when the final prosthesis will be considered. Keep the instructions for the temporary restoration's permitted use with that stage of the plan. A temporary tooth's appearance does not identify its loading instructions.
Bring these questions to the consultation:
- Which arch and teeth does the plan cover?
- What determines the timing of the first and final restorations?
- What could change the planned sequence?
- Who provides the follow-up care?
Ask what the quotation includes
Request an itemized quotation that identifies the proposed treatment stages and any separate maintenance charges. Use the implant cost discussion to prepare questions, rather than treating an old online price as a current offer.
Plan access for continuing care
Ask the team to demonstrate care for the restoration you will receive. The All-on-4 cleaning guide focuses on that daily-care discussion. Professional ultrasonic cleaning concerns a separate maintenance setting.
Record changes between visits. The bleeding and baseline guide explains how to describe a tissue concern without deciding its cause from appearance alone.
