牙齒都可以修改外形?

外形修改(Contouring)

為了令牙齒看來更齊整,真牙的外形可以修改。如牙齒過長,便可把它修短;如牙過寬,則可把它修改令其於視覺上收窄


程序:
倒模後,在牙模上加工製造模擬效果(3-D Diagnostic wax-up),牙醫亦可於病人牙齒以黑筆塗去擬修改部份,製造摸擬效果。
優點:
價錢相宜,簡單,快捷
缺點:
只適用於輕微參差的情況




牙齦修改(Gum Contouring)

牙齦修改是把牙齦推高,適用於牙齦不對稱的情況。如門牙過短,便可把牙齦推高,令牙冠長度增加。如微笑時牙齦外露過多
(Gummy Smile),牙齦修改亦可大大改善此情。



瓷粉黏合 (Bonding)

利用瓷粉
(Composite Resin) 加在參差不齊、啡黃色、受損或破壞的牙齒表面上,能夠改善其色彩、外觀及排列。瓷粉黏合亦適用於蛀牙、斷牙或門牙空隙。但瓷粉不是很堅硬,故容易損毀或鬆脫。
優點:
價錢相宜, 簡單,可作緊急用途或當作塘瓷牙面前過渡期的補粉
缺點:
只能維持三至五年,視乎飲食習慣,故要避免喝茶、咖啡及吸煙,因補粉會磨蝕及變色

應隔多久檢查牙齒一次?



對一般人來說,可每年檢查牙齒一次。但一些高危或有特別需要的人士,就需要6個月檢查口腔一次。這些有特別需要的人士包括:

弱能人士
由於弱能人士在保持基本口腔 生方面出現困難,他們會深受牙周病及蛀牙的威脅。

頭部和頸部曾接受電療的人士
在電療過程中,口腔的正常組織會受影響,引致唾液分泌減少、口腔黏膜發炎等及容易患上蛀牙及牙周病。


吸煙人士
吸煙者患牙周病的機會比非吸煙者高出至少五倍。


患有嚴重口腔疾病人士
一些患有嚴重蛀牙、牙周病、口腔癌、裂顎…等人士,需要接受較頻密的口腔檢查,以確保口腔健康。


患有系統性疾病人士
患有糖尿病、血友病、愛滋病等人士,身體的免疫系統會受到妨礙,抵抗病菌的能力相應降低。如果口腔不夠清潔,在牙齒表面的牙菌膜就會十分容易引致牙周病。並且,牙周病的病情會迅速惡化,變成嚴重的牙周病。

糖尿病患者 應注重口腔清潔



港人對糖尿病及牙周病這兩個名詞不會感到陌生,但只有少數人知道糖尿病人是牙周病的高危族。研究顯示,糖尿病患者牙周組織免疫力較一般人低,容易誘發牙周 病。同時,他們口腔唾液內血糖含量較高,易與細菌產生化學作用,形成酸性物質腐蝕牙齒,增加患牙周病風險。加上患者口腔唾液分泌少,易口乾,令細菌及牙菌 膜在口腔內積聚,在未能及時清潔的情況下,分泌酸性物質腐蝕牙齒,產生有毒物質,刺激牙齦等牙周組織,導致牙周病等口腔疾病。

降低糖尿病患者牙周病的風險,需有效控制血糖及維持口腔衞生。由提高自身免疫力着手,降低口腔內血糖含量,改善口乾問題; 同時,更應注意日常的口腔保健,盡量減少口腔內細菌及牙菌膜堆積。建議每日至少刷牙兩次,於每次飲食後刷牙為最佳,能及時清潔殘留於牙齒表面的牙菌膜。然 而,單靠刷牙並不能全面清潔口腔,有研究指出,單靠刷牙只能清潔百分之二十五口腔表面,仍有百分之七十五布滿細菌,成為口腔疾病的溫床。

因此,建議同時配合使用牙線,及含抑菌成分的漱口水全面清潔口腔,降低患牙周病的風險。

全陶瓷牙冠的安裝程序 (Part 1)


如果想要安裝新的全陶瓷牙冠,第一個步驟便是由您的牙醫師針對您目前的牙齒情況進行檢查。


如果牙醫師判定您的牙冠已經無法進行修復且需要更換為全陶瓷牙冠,牙醫師便會開始為您的牙齒進行前置准備作業,以利新牙冠的安裝。

牙醫師將會重塑您的牙齒形狀,以騰出用來容納牙冠的空間,如此便完成了牙齒的前置准備作業。大部份的牙醫師都會在進行這道牙齒削減步驟時,為病患施行局部麻醉。接下來,牙醫師會為您口中需要安裝牙冠的部位制造印模。

牙齒印模是使用彈性材料為病患口腔制作的一種「負模」。 (續)

Improve your smile? Artificial Crowns and Veneers?



Periodontal plastic procedures can give you a perfect smile and boost your confidence so you can be at your best. Cosmetic surgery has become more popular than ever before especially now that people are living longer and aging more gracefully with the help of plastic surgery. Periodontal plastic surgery has also felt this trend as it has experienced a significant shift toward cosmetic-related surgery to help make smiles last a lifetime.

 

1) Artificial crowns
A dental crown is a customized tooth-shaped "cap" that is placed over a tooth - covering the tooth to restore its shape and size, strength, and/or to improve its appearance. The crown can (i) protect a weak tooth from breaking; (ii) restore tooth that has been severely worn down; (iii)  Cover misshapened or severely discolored teeth.  Preparing a tooth for a crown usually requires two visits to the dentist -- the first step involves examining and preparing the tooth and the second visit involves placement of the permanent crown. 
 

(2) Veneers
Severely stained or chipped teeth may require Veneers, ultra-thin sculpted pieces of tooth-colored porcelain that fit over the front of your teeth.
At first, the dentist will check and examine your tooth. To prepare a tooth for a veneer, your dentist will remove the enamel from the tooth surface, which is an amount nearly equal to the thickness of the veneer to be added to the tooth surface. Next, your dentist will make an impression (mould) of your tooth. The veneer color can be adjusted with the shade of cement to be used. Next, your tooth will be cleaned, polished, and etched -- Once properly position on the tooth, your dentist will apply a special light beam to the dental veneer, which activates chemicals in the cement causing it to harden or cure very quickly. The final steps involve removing any excess cement, evaluating your bite and making any final adjustments in the veneer as necessary.  The Veneer could be removed technicially by dentist if needed.
