Dental Implant (1)

 
 
What patients suitable for dental implant?

When there is shifting in your teeth and your teeth stat to loose, e.g. periodontal disease, it is suitable for you to undergo dental implant treatment. There is no age limit for dental implant. However, it may not suitable for teenagers as their development of skeleton have not completed yet. Besides, patients with severe diabetes, osteoporosis, kidney disease, AIDS, insufficient bone in the oral cavity or severe fear of dental implant is not suitable for dental implant. In fact, dentist will undergo clinical examination first, and then use digital tools to predict the tooth location and dental implant size. After these procedures, dentist will decide whether the patient is suitable for dental implant.


What are the processes of dental implant?

After anaesthetic injection, the dentist will remove the tooth from upper jaw or lower jaw. The dentist will then sterilize the gum, mount the dental implant which is made of titanium or titanium alloy with the bone of oral cavity. After that, the dentist can take the impression of the teeth. The impression of the teeth is used to produce tailor-made dental bridge. After few hours, temporary dental bridge will be produced. Dentist will mount the dental bridge with the dental implant by screws. After about 3 months, when the dental implant has combined with the jaw bone and the gum shrinkage has reached a stable condition, the dentist will help the patient to produce the impression of teeth and implant again and complete the dental implant process.

Dental implant is made of titanium alloy which is biocompatible. It can support the artificial tooth firmly. Besides, the dental bridge and artificial dental crown used in dental implant are made of porcelain, resin and other materials, which are very durable and solid. Dentist will choose materials according to the condition of the patient. Under general condition, the surgery of single dental implant is required for half an hour. For the dental implant of the whole upper jaw or lower jaw, the surgery is required for about 1 day.


The differences between dental implant and traditional dental bridge:

The stability and the bite force of traditional dental bridge are poorer, which will affect the sensation of mastication. Besides, traditional dental bridge have to be taken off and cleaned every day. Moreover, the teeth nearby have to be reduced in size in order to wear the traditional dental bridge. This will affect the dental health of the nearby teeth and cause resorption of alveolar bone.

On the contrary, dental implant requires only 4 to 6 artificial implant which can support 10 to 12 artificial teeth. They can be fixed inside the oral cavity and do not need to be taken out. They are very firm, time saving and convenient. Furthermore, dental implant will not cause any harm to other teeth. Porcelain dental crown is also very durable. The chewing sensation after dental implant is almost the same as that when chewing with real teeth.

牙科美容 -人造牙冠 (Crown)、牙貼面 (Veneer)




適當的牙科護理及治療可改善牙齒外表,助你展露動人笑容,增加自信心,增添美麗及魅力而漸受歡迎。牙科美容因可令人展露動人笑容一生,同樣漸受重視。

人造牙冠 (Crown)
人造牙冠即以物料做成牙冠套,套於原有的牙齒上。如遇牙齒過份擠迫或開始鬆脫等,除會影響外觀,亦容易堆積牙菌膜,繼而引起牙周病,甚至導致咀嚼困難等。

可選擇進行人造牙冠,牙科醫生將因應患者需要,配造不同人造牙冠。





首先,牙科醫生會磨細牙齒並套上臨時牙冠,然後印製牙模及牙齒咬合位置,最後以黏合劑將人造牙冠套於牙齒上。


牙貼面 (Veneer)
牙貼面即以全瓷牙貼貼於牙面,遮掩原有牙齒之缺陷。

牙貼面治療簡易,先由牙科醫生作檢查,將牙齒表面磨去少許,印製牙模及牙齒咬合位置。三星期後覆診,牙科醫生清潔牙齒,並粘貼牙貼面於牙面,過程約需一小時。


由於牙貼面不會磨掉原有牙齒,需要時可依個人需要拆走牙貼面,恢復牙齒原狀。

口腔常識




牙痛
蛀牙會引致牙痛,特別當進食冷、熱、甜、酸的食物的時候。如果蛀壞的部分深入牙髓,牙髓便會受細菌感染而發炎,引致更劇烈和持續的痛楚。其實牙痛的成因十分多,所以如果您有牙痛,必須接受牙齒檢查,才能得到正確的診斷。
 
 
牙齦痛
牙齦痛的成因可能是牙齒長出、口瘡(俗稱「飛滋」)或者牙周病。如果您有牙齦痛,應請教您的牙科醫生,才能得到正確的診斷。
 
 
牙齒變色
牙齒變色分為外在和內在兩種類別。
 
內在變色的成因包括:在牙齒形成過程中吸收了四環素或過量的氟化物、牙齒受碰撞而導致牙髓壞死、牙齒上存在含金屬的補牙 物料等。
 
這些情況通常可以透過補牙或漂牙來改善。外在變色主要由咖啡、茶類、中藥或煙草造成。這些附在牙齒表面的斑漬,只要透過洗牙便可以清除。
