hygienic pontic
Hygienic Pontic is short word yet with wide means so we summary it in special article
hygienic pontics in dentistry : The hygienic pontic meets the requirements for keeping a healthy environment.
Since the periodontium doesn’t make contact with the underlying soft tissue,
gives the abutment tooth simple access for oral hygiene tools to clean it distance between However, the pontic and alveolar ridge are substantial enough to hold food particles and to allow the entry of the tongue .
As a result, pontic should only be employed in the posterior portion of the mandible due to functional and, above all, cosmetic and phonetic drawbacks.
Concavity’s surface Pontics floss can make more of an impact on the ridge in modified ridge lap.
tissue surface, however there is still a concave area in the middle of the tissue-contacting surface
cannot be gotten rid of
When employing the, chun – linsteeve claims that the following benefits can be pontic modified ovals
1. Excellent Aesthetic due to the correct emergence profile it generates.
2. A cleaned case compared to an ovate pontic.
3. More cleaning cases compared to ovate pontic
4. Removing or minimizing the black triangle that appears between the teeth
5. A strong air seal that prevents saliva or air leakage.
If the alveolar ridges are devoid of flaws, the saddle pontic produces very esthetic results . The emerging profile, which resembles that of a normal tooth very much,ensuring no palatal gap develops, which could result in phonetic issues. However, today, it the considerable concave contact, it is generally agreed that this approach should not be used.
Adherent plaque cannot be removed in the vicinity of the alveolar ridge. Clinical recollections involve
There are soft tissue alterations, significant inflammation, including ulceration, and 85 percent of the pontics
Ridge lap Pontic:
Because the basal contour remains concave and is inappropriate to give a tight contact for the dental floss, reducing the surface area does not considerably enhance cleanliness underneath the pontic.
Pontic ovate modified:
The modified ovate pontic design was created live in 2003 to solve the ovate pontic’s issues without using it. pontic dental floss ridge in the pontic tissue cannot be touched.
altered ridge lap This particular pontic is made to have the saddle lap over the Only the occlusal side. The lingual design is determined by the size, shape, and ridge of the tooth. Itexposes the lingual ridge as it curls in. Compared to the full ridge lap pontic, it is cleaner and more aesthetically pleasing.
Pontic Ovate:
This kind is intended to resemble an egg or a bullet. It is best for teeth at the front;
However, because it is highly esthetic and cleanable, its use is not restricted to posteriors.
It is createdb y creating a depression in the remaining tissue ridge that resembles the original root’s form.
both Crown. The tooth appears to be emerging from the gum tissue rather than merely resting on
Additionally, the Ovate offers the best esthetics and requires the least amount of upkeep.
The ideal option is pontic
Pontic Design Principles: The mesio distal width, buccolingual dimension, and ocelus cervical distance of the remaining ridge need to be carefully assessed. To create a pontic that complies with sanitary Inviting the tissue is subject to requirements and prohibitions, therefore one must pay attention to the form.
mechanical concepts must be incorporated into the design and shape for strength and endurance.
Basic biological concepts
These include a tissue surface that can be cleaned, easy access to the abutment teeth, and no strain on the ridge .
Fundamentals of mechanics:
Teeth, rigidity to withstand deformation, robust connectors to avoid breakage, and selection of material to prevent porcelain fracture .
aesthetic standard These must involve mimicking the appearance of the missing tooth, appearing to “grow” out of the
ridge and include a porcelain design area
Recent developments in pontics include the anterior implant of porous coralline hydroxyapatite blocks. Several patients enhance the link between the pontic or ridge in fixed prostheses, increasing aesthetic and oral hygiene abilities. The maxillary Intervention embrasures can be filled
Pink porcelain is used in the anterior region to enhance the appearance of the fixed partial denture.
The aesthetic issues could potentially be resolved with the pink porcelain. produced by
between the pontic and abutment, there is a modest amount of ridge resorption and papilla loss.
Glass-infiltrated alumina, lithium-disilicate glass-ceramic, tetragonal stabilized zirconia, and are currently useful for three-unit bridges. Three-unit bridges constructed of Ceramic and glass materials made of lithium disilicate were developed to repair lost teeth up tothe first premolar, where a 16 mm2 cross-sectional area is suggested for the connector. In 2005,
The market has recently introduced to an enhanced press ceramic material known as IPS e.max Press. Information about IPS e.max Press ceramic is scarce . This ceramic tile is pressed aimed to increase Empress 2’s possible indicators. even though it has comparable physical
Its translucency has enhanced and shares the same qualities as the latter . System for IPS e.max Press
includes a lithium disilicate (2 SiO-)-based high-stability framework material.Li2O) .
The restorations can be modified in two ways: either utilizing a layering process that is based on ceramic, glass, or fluorapatite, or by applying a stain. as far as possible
As far as is known, there hasn’t been any research on the durability of implant-supported IPS e.max Press restorations.
Because they have helped overcome some of the drawbacks associated with artificial solutions, dental implants have emerged as a trustworthy substitute in the management of total lack of teeth. studies assessing the long-term outlook for implant-supported
Publications about restorations exist . It is widely acknowledged that the capacity of bridges relies largely on the size, but also on the characteristics of the ceramic material. on the span of the pontics, the construction, the shape and placement of the connectors, process, the crowns’ surface polish, and the luting procedure.
For circumstances that call for pontics in the creation of, pontic designs were well explained. partials that are fixed. Saddle (ridge lap), modified ridge lap, and sanitary are a few of these types. Conical, ovate, and (sanitary). Bridge pontics must meet esthetic, mechanical, and requests for prosthetic dentistry that are practical and clean. Designing properly is more crucial for cleaner and healthier tissue than the material selection. Alveolar resorption and remodeling change the form of the edentulous region after teeth are lost.The ultimate ridge shape after healing could deviate much more from the initial design. The loss of a tooth may also have an impact on the adjacent and opposing teeth.
a tooth opposite the gap can start to float away from its socket. In these situations, changes must be made for pontic in terms of basic tooth morphology. In a prosthesis, stress distributions can be highly complex
a The typical stress pattern can be adjusted if the pontic design is changed to increase the all-ceramic bridges supported by implants’ period of survival.
