The use of processed silicone to retain the implant-supported tissue-borne overdenture

Resilient liner vs. clip attachment effect on peri‐implant tissues of bar‐implant‐retained mandibular overdenture: a 1‐year clinical and radiographical study

“…1a). In case of resilient liner‐retained overdentures, plaster indices (Adrian et al 1992) were made over the trial dentures to ensure that the space between the bar and the teeth was enough for the resilient liner and acrylic resin. Aluminum foil sheets of 2–3 mm thickness (Wright 1976) were applied over the bars to provide space for the resilient liner, and the dentures were processed.…”

“…Overdentures may be retained using splinting attachments (bars and clips) or non‐splinting attachments (ball and sockets, magnets, telescopic copings and stress‐breaker attachments) (Preiskel 1985; Block et al 1990; Esfahani et al 1997). The main disadvantages of bars and clips are rapid wear, limited rotational freedom, bulk and soft tissue proliferation in unobturated regions under the bar (Adrian et al 1992).…”

“…Resilient denture liners have found increasing favor in several applications in prosthetic dentistry, including their use with dental implants for retention (Kiat‐Amnuay et al 1999). When used as a method of retention for implant‐retained overdentures, these liners are wear resistant, partially obturate the space under the bar, absorb energy, distribute masticatory forces to the implants and edentulous ridge and provide greater latitude of movement and comfort to the patient (Adrian et al 1992; Kiat‐Amnuay et al 1999). Shaygan et al (1993) found that resilient denture liners offer more retention, which even when diminished after multiple insertions, was still greater than with bars and clips.…”

“…Although several studies reported the use of resilient liners as a female housing over bar (Adrian et al 1992; Kawano et al 1993) and ball (Joseph et al 1998) attachments for implant overdentures, the effect of this type of attachment on peri‐implant tissues was not a concern. Therefore, the aim of this study was to evaluate the peri‐implant tissue health of mandibular overdentures retained to the implants using resilient liner or clip attachments.…”

Effect of Net Fiber Reinforcement Surface Treatment on Soft Denture Liner Retention and Longevity

“…They are used to enhance the fit of poor fitting dentures and prevent trauma to sensitive mucosa, by forming a cushioned layer between the denture base and the oral mucosa 2–4 . They aid in the retention of extraoral prostheses and intraoral devices by engaging overdenture‐bar attachments 5,6 or modified abutments 7 and undercuts present in defect sites such as in maxillofacial obturators 8 . Denture liners should be elastic, nontoxic, and nonirritant to oral tissues.…”
