The McGill Consensus: two implants under the lower denture
Since 2002 there has been an international consensus — the McGill consensus, reaffirmed in York in 2009 — which states something uncomfortable for the sector: for an edentulous jaw, the conventional complete denture It should not be the only treatment offered. The recommended minimum standard is two implants that they secure the lower denture with attachments.
The resulting overdenture remains removable: it comes out for cleaning, just like before. The difference is that it stays still when chewing and speaking — exactly what a conventional lower [denture] cannot promise regarding a receding bone. Studies comparing both options find improvements in satisfaction, quality of life, and chewing ability.
And now the other half, which also has to be said: the attachments wear out. Its retention parts are replaced periodically — it's normal maintenance, and it should be included in the conversation with the quotation in hand, not pop up afterwards. In the upper jaw, the anatomy usually requires a minimum of four implants, so the rule of two is specific to the mandible.
We are telling you this as information you are entitled to, not as pressure: the decision is yours, and a well-made conventional denture remains a dignified option.
