Dentures NYC — Full and Partial Dentures at Centre Dental

A complete (full) denture replaces all the teeth in an upper or lower arch and rests on the gum tissue, held by suction, a border seal, and muscular control — the upper is usually more stable than the lower because the palate adds surface area. A partial denture (an RPD, or removable partial denture) replaces some teeth and clasps onto the remaining natural ones for retention, made from cast cobalt-chromium metal or a flexible thermoplastic. An implant-supported overdenture combines two or more dental implants with locator attachments — the denture snaps onto the implants for dramatically better stability while still lifting out for cleaning. The right option depends on your remaining teeth, bone volume, and how much the looseness of a conventional denture affects your life. We map all three at the consultation, using the Centre Method.

The artificial teeth are typically high-grade acrylic resin, and the denture base is a gum-coloured acrylic. Their size, shape, shade, and midline position are chosen with you at the try-in — not guessed at by a lab. A properly designed denture restores the lip and cheek support that collapses inward when teeth are missing, which is why so many patients feel their face looks fuller and younger afterward. Old photographs are genuinely useful here: they let us rebuild the smile you recognize rather than a generic one. If you're also considering brightening or reshaping any remaining natural teeth, we can coordinate that with cosmetic treatment so everything matches.

The lower complete denture is the one patients struggle with most, because the tongue and a smaller ridge give it little to hold onto. According to PubMed, the 2002 McGill Consensus Statement — an international expert panel — concluded that a mandibular two-implant overdenture should be the first-choice standard of care for edentulous patients, rather than a conventional lower denture (Feine JS et al., Gerodontology 2002 / Int J Oral Maxillofac Implants 2002). The functional difference is measurable: in a crossover clinical trial, patients needed only 40 chewing strokes with a two-implant overdenture to reach the same food breakdown that took 69 strokes with a conventional denture, and reported significantly higher satisfaction (Sharma AJ et al., 2017). A separate randomized trial found even a single mandibular implant significantly improved chewing efficiency over a conventional denture (Rocha COM et al., 2021). None of this means everyone needs implants — it means, if a loose lower denture is your problem, implants are the evidence-backed answer, and we'll tell you honestly whether your bone supports them from a CBCT scan.

New dentures take about three to six weeks to feel normal. Speech recalibrates — reading aloud speeds it up — and eating improves as you learn to cut food smaller and chew on both sides at once. Conventional dentures are removed at night so the gum tissue can rest and recover, then brushed daily with a denture brush and a non-abrasive cleaner; regular toothpaste is too abrasive and etches micro-scratches that trap stain, and hot water or bleach can warp or pit the acrylic. Over the years the ridge underneath keeps changing shape, so annual exams and periodic relines — typically every few years — keep the fit snug. An implant overdenture is cleaned the same way, with added attention to the locator attachments and the gum around each implant.
